I tried a reversed sharing and it worked!!
Instead of sharing from the main account where we have all the information, i shared a folder from the previous "destination" account to the previous "sending" account and it worked!! This won't solve my problem, but maybe it can help someone to mitigate their issues with this problem.
I also noticed that on the accounts that have NO "Search" on options the sharing experience is different from the accounts that HAVE "Search" on options, and i now think the accounts that have NO "Search" on options are the NEW ones, keep reading...
About the versioning, i wondered if the OneDrive site had any kind of version, so i investigated the page source and i found different versioning between the accounts, here are some examples:
Account currently sending the shared folder:
https://res-1.cdn.office.net/files/odsp-web-prod_2025-02-07.009/odclightspeedwebpack.manifest/plt.listviewdataprefetch.js
https://res-1.cdn.office.net/files/odsp-web-prod_2025-02-07.009/odclightspeedwebpack.manifest/186.js
Account currently receiving the shared folder and not working as it should:
https://res-1.cdn.office.net/files/odsp-web-prod_2025-02-14.011/odclightspeedwebpack.manifest/plt.listviewdataprefetch.js
https://res-1.cdn.office.net/files/odsp-web-prod_2025-02-14.011/odclightspeedwebpack.manifest/188.js
Notice the different versioning? I think this is what is causing the issues:
1. Folder sharing between same versions - WORKS
2. Folder sharing from new version to old version - WORKS3. Folder sharing from old version to new version - DOESN'T WORK
I really hope this is useful to help fix the issues!!
