I was able to post yesterday using Memmy, and today Voyager worked (all of this was from my instance to Lemmy.world) The error I was getting yesterday would happen when I selected a photo. It would spin and then give the error before I had written the title/text or tried to post. It was like it was failing to fetch the image link from imgur. Thankfully it seems to be working again. Love the app, thanks for all your hard work!
Just noticed my ninja account is working again!
