I frequently use GroupMe on desktop from Firefox, on two separate computers (a self-built desktop, and a Dell Latitude laptop). Starting sometime over a week ago, I have been unable to drag & drop or otherwise upload photos in my chats. The only method that works is pasting direct URLs of JPGs. In all other circumstances, I get the uploaded image error attached to this post. Two different GroupMe support agents have said that, since image upload is still working in Edge, that it's a Firefox problem. Tried clearing cache, site cookies, reset the browser, ran in troubleshooting mode...same result every time. This is '''''not''''' the "image file size too big" error. I used to routinely post captures from the Snipping Tool, and I can't anymore. I'm not sure where else to go to troubleshoot this. It's very annoying. Any suggestions?
