Fix a row before it is skipped

Too-long captions and comments are caught on the review screen and can be edited there.

Title, first comment and description are checked against the limits of the platforms you ticked for that row, before anything uploads. A row over a limit shows the problem and opens editable Title, First comment and Description boxes with a character count. Fix the text there. Schedule stays disabled until every row is clean.

Your edits are used for the post. The sheet file itself is not changed.

Common limits

Rows with sheet problems (such as an unreadable date) are listed as "can't be scheduled" and skipped. Fix them in the sheet and upload again.
