Error on uploading team avatar

Avatar is png and 500x500. On page edit team and uploading logo gave this error:

Error! The avatar field is required.

Are there any fix for this?

I have the same issue. Tried with multiple image types and dimensions, still receive Avatar field is required right after upload.

It says changes are saved, but avatar is still default one.

I also have problem uploading team avatar. I also have tried different types and sizes of an avatar image. But nothing changed. I always get this error:
Error! The avatar field is required.

Same here

This issue is fixed for me =)
