Seems like there is a problem between PieFed and the Voyager App

I was looking at Voyager on my phone and saw communities I hadn't subscribed to in my home feed, and upvotes on posts I hadn't voted on (or even seen before). When I tried to remove the upvotes, a message said "problem voting, please try again".

Thankfully, when I view PieFed through Firefox, these problems don't exist, so it must be the app. Not overly surprising since it was initially developed for Lemmy, I believe.

Not sure what changed to cause this problem or whether the change was in Voyager or PieFed.
