SOLVED : That was a misconfiguration.. (https://piefed.social/comment/1218522)
It's strange.. I cannot see some of my recent posts. If you go on my profile, you cannot see the recent posts, the last on is about 2 weeks.. If someone has a solution ! thank you
EDIT : I can see this post on my profile but it's missing loads of others between two weeks and today...
Your account is on lemmy.ml, which had some downtime the other day to test a beta version of the 0.19.4 release. Unfortunately, there were major performance issues and the admins had to revert to the old version and go back to a backup of the database from before the upgrade.
While I can't guarantee that's the cause of your issue, it would explain why users from other instances aren't having the same problem.
Glad to see you resolved your issue. I'll be the first to admit that the UX around languages is unintuitive and janky at the moment.
Have you been playing with language settings? This post is in 'Akan', but your previous posts are a mix of 'English' and 'Undefined'.
If you've removed 'English' as a language you understand, the posts from 3 hours and 3 days ago won't be visible to you.
Maybe the instance... I've tried on lemmy.ml, phtn.app and jerboa on my phone...
