Do you have accounts logged in on more than one instance? One of my accounts is with an instance that just updated to the Lemmy 0.19 beta yesterday which doesn’t with with all clients. Once I removed that account from LiftOff everything went back to normal.
There are a lot of PixelFed instances, this might get complicated.
I’d ask for https://miniature.photography but I’m one of only a dozen or so people who post there.
