Yeah, avatar swaps on mobile are a pain. Works great on browser but glitches out on phone. I finally nailed a steady selfie for mine using the iPhone timer. I personally followed https://skylum.com/blog/how-to-take-a-timed-photo-on-iphone to ditch shaky shots and it uploaded sharp. Hope they patch it soon!
Totally feel you, mobile avatar swaps can be super annoying. Smart move using the iPhone timer though—that’s actually a solid workaround. Glad it helped you get a clean shot. Fingers crossed they fix the mobile glitches soon. animal craft
