Recently ran into a hiccup where a "Move Row" action did not fully complete when an automation was triggered again and resulted in rows stuck unable to move to another sheet.
I reached out to support and was advised to update the timing of the workflow to a time basis to prevent the issue from reoccurring.
I tried to update the automation to set the workflow to run the trigger on an hourly basis and that is when I received the error message it is not allowed when the action is "Move a Row" or "Copy a Row".
To help prevent issues, it would be helpful to allow these automation actions to occur on a time basis in addition to "when triggered."
