Troubles Migrating Multisite-Language-Switcher Wordpress Multisite (in a sub-folder) from Local to Dev - wordpress

Question

I am having trouble migrating a Wordpress Multisite from my local environment to a subfolder Wordpress install on the development server.
I opted for exporting the local database using WP Migrate DB Pro, which takes care of the search and replace for the base URL, and then importing the SQL file via phpmyadmin into a blank multisite on the remote dev server (I explain the steps I took in detail below).
(Note: I cannot use the WP Migrate DB Pro plugin to push the multisite because my main site is not in the server root. Delicious Brains support wrote: I can confirm that migrating between a subdirectory multisite and a subdomain multisite is still not supported by WP Migrate. This is why I am trying this method of importing the WP database directly via phpmyadmin.)
Here is the situation in the current state of the migration.
After the migration, on the user end, some things worked, and others didn’t. The “main” site of the multisite is completely intact. All pages can be viewed with all images in place. This is the English site. On the other two sites of the multisite, the French and the Spanish, all pages fail to load and go to “THE PAGE CAN’T BE FOUND. It looks like nothing was found at this location.” error page. (note: we are using the Multisite Language Switcher plugin to create a multilingual site).
On the WP Admin side, again everything works for the English site, but not for the French and Spanish sites, nor the Network Admin. The “My Sites” admin dropdown menu shows all of the subsites of the multisite as it does in the local environment. But when clicking on the French or Spanish subsite “Dashboard” links, the main site dashboard is loaded (i.e. English) not the expected French or Spanish dashboard.
There is also a problem with the Network Admin dashboard. When “Network Admin -> Dashboard” is clicked it goes to “This page isn’t working | *****.org redirected you too many times. | Try clearing your cookies. ERR_TOO_MANY_REDIRECTS”.
Note that the database import worked well. All the tables are there for all subsites. And because I simply replaced the remote /Content folder with the one from local, all the files are in place for the multisite.
These are the URLs:
main site (English): https://inrichnetwork.org/cicada10/ ;
secondary site French: cicada10/fr/
secondary site Spanish: cicada10/es/
Here are the steps that I used to migrate the multisite from the local environment to the remote development server:
Create a new WP install on remote site in a subfolder /cicada10
Make remote site a multisite by following these instructions: https://multilingualpress.org/docs/how-to-install-wordpress-multisite/
Export DB on local using WP-Migrate DB Pro “backup option” (In the migrate tab select “REPLACE ANOTHER SITE WITH THIS SITE | Export Database”. I used: “Option: Export Entire Network”; “Option: Export all tables”; Remplace: Find //cicada.local Replace with https://inrichnetwork.org/cidada10/ | Find C:\Users\User\Local Sites\cicada\app\public Replace with /home3/centrele/public_html/cicada10.)
Extract exported database .gz file to get SQL file
Create Zip of the WP /Content folder on local
Gather database information using phpmyadmin from the local WP multisite install (Get from wp_site table: domain = inrichnetwork.org / path = /cicada10/)
Drop all tables from remote DB using phpmyadmin
Import DB backup SQL file from local into empty remote DB using phpmyadmin
Rename WP /Content folder on remote and then upload Zip of /Content from local via file manager, and unzip, delete Zip file
Verify in phpmyadmin Site URL in all language wp_options(2,3) tables is https://inrichnetwork.org/cicada10
Change wp_site on phpmyadmin to table: domain = inrichnetwork.org | path = /cicada10/
Edit wp-config.php ($table_prefix = *to the prefix of remote db | Be sure that the multisite paths are correct: define( 'DOMAIN_CURRENT_SITE', 'inrichnetwork.org' ); define( 'PATH_CURRENT_SITE', '/cicada10/' ))
Sign back into remote WPAdmin and refresh the page
Any help getting the secondary sites properly connected and the Network Admin working would be greatly appreciated.
