Will my posts be moved also?

What about the posts from other people that I saved/favourited to see later? How can I keep them

Yes

Ps: On Android apps, this problem is fixed after logging out and logging in again

Hi, all my bookmarks got totally messed up: I lost some bookmarks and for new bookmarks I never asked for.

This happens for instance on the “Traditional art” Community.

Could you please have a look?

Thanks
