This occurs both within jerboa and through a desktop browser. The posts still exist and can be viewed through accounts on other instances. I still receive notifications when comments are made and can view them in my inbox. When clicked they take me to the post but i am unable to view comments on the post.
The only posts viewable on my account through lemmy.ml are ones made on lemmy.ml communities so im assuming its a federation problem. I also noticed that some posts are only viewable from certain instances but not specifically the instance that the post was made on. For example i made a post on [email protected] and this post is on my lemmy.ml profile when viewed through a lemm.ee, sh.itjust.works, or a lemmy.world account but not when viewed through my lemmy.ml account.
Im assuming whether or not a post is viewable on my account depends on the viewers federation with the instance that hosts the community the post is on but this does not explain why my lemmy.ml account cant see its own posts.
Maybe this is just part of defederation and not a bug but i dont bother keeping track of who federates with who
