This has already been reported, but I wanted to share this information in case anyone else catches this bug.
If you upload or edit a submission from a mobile browser, the Keywords input field might not process your text correctly. It seems that commas are not functioning as they should. Normally, they are supposed to end a keyword so that the next text you type will become a new keyword. The bug is preventing that action.
To get around this issue, rather than typing a comma, press the Enter key instead.
