Bug: Upload Waiting for User Input v1.50

[catch-point]

When I use the upload command !U, the UI gets stuck on "Upload Complete" and does not continue with the script. It appears to be waiting for user input before it will continue.

For example the following command will only upload one video and will eventually run out of battery while on the "Upload Complete" screen. !14:00NmTp.60!S!60E!U!1R

Same thing for motion detection when uploading, only the first video gets uploaded, no other video is recorded. !SM3D4H5!U!R

I am using Hero Black 10 H21.01.01.50.70

!U worked for me as expected before I upgraded to 1.50. However, I downgraded back to H21.01.01.46.70 and similar issue to this (waiting for user input) now occurs.
