Sudden decrease in votes on apocalypticart@feddit.de after 0.19 upgrade

cross-posted from: https://lemm.ee/post/18778701

This is the chart of the votes for the latest posts on !apocalypticart@feddit.de.

This may be just a coincidence, but I find a bit weird that the votes went down to almost zero exactly when lemm.ee[^1] and feddit.de[^2] upgraded to v0.19.

EDIT: From a comment by @Fleppensteijn@feddit.nl in the original post:

I’m getting a LemmyAPIException when I try to upvote since yesterday. Now I notice I’m getting the same error when I try to post from the app.

EDIT-2: Another comment by @maegul@lemmy.ml:

the question then becomes when the last post was made to apocalyptic art. From my quick glance it was 4 days ago on the lemmy.ml mirror, which seems behind the most recent posts on the actual community. Lemmy.ml is on the newest version.

So my guess is that there’s some general federation issue, possibly on the feddit.de end, which is causing some things to get dropped.
