I’ve also been building a lemmy web client (Quiblr) and I can tell ya that these types bugs often come up due to API issues. Honestly, it can be difficult at times to know if it is actually an API issue or if it is an app bug. So app bugs go unresolved because they get written off as API issues lol The alternative is that you invest a lot of time trying to fix something, only to realize that it is out of your control
I think Lemmy’s API issues will be fixed, but the growing pains are definitely there!
