Hello @nada,

We found an issue relating to screenshots on the new iOS and MacOS operating systems where screenshots have a hidden Unicode character (\u202f) in them. This Unicode character was causing failures for file uploads to the Sendbird server. The file you attached to this post contains the same Unicode character.

We have since deployed a backend fix to check for this character and you should not encounter anymore issue when uploading files to Sendbird.
