I made a post on a community on lemmy.world : https://sopuli.xyz/comment/1128916 .
A reply was made to this post that can bee seen when viewed from lemmy .world : https://lemmy.world/post/1354014 , but not when viewed through sopuli.xyz : https://sopuli.xyz/post/1218178 and I did not receive a notification of this.
I also noticed that a number of this users posts were missing when viewed from sopuli.xyz : https://sopuli.xyz/u/[email protected] they can be seen when viewed from lemmy.world : https://lemmy.world/u/setsneedtofeed .
I have notified the [email protected] and he is contacting the admins at lemmy.world and I thought I should do the same with sopuli.xyz as I have no idea where the problem is occurring.
Thanks, if there is any other info that might be useful let me know and I will endeavour to help.
The easiest answer might be that there is a delay in federation between the instances.
