Steps to reproduce

1. Setup automatic upload of camera roll
2. Record some very large videos (over 10GB)
3. Open Nextcloud app to let it upload the photos

Expected behaviour

Videos should upload as expected

Actual behaviour

Transfers shows repeating retries to upload with error message: "Error, waiting to upload - 3 min left to retry" and "No enough memory"
I also tried completely restarting my phone so that Nextcloud was the only app that had been started, and it continued with the same behavior.
