First Upload Photo/Videos - Talk Android-App

Hello,

When uploading, for example, photos, the first upload always fails. After that, the upload works regardless of the file size or how many files need to be uploaded.
A few hours later - the same problem occurs. The first photo/video upload always fails.
I am using Talk version v19.0.1.
Other users with different smartphones and Android versions, or Talk versions, are experiencing the same problem.
Uploading via browser works without any issues.

Thank you and best regards,
Mike
