As you know, we were affected by the federation delay problem at 0.19. Lemmy developers made fixes for this, but they haven't released the new version yet.

I selected the commits with these fixes and ran that version on Lemy 2 days ago and the problem seems to have fixed according to Federation state tool.

Glad we finally got rid of a mud solution like restarting the server periodically :) Please contact me if you encounter any problems about this.
