If you have reached your priority generations limit you can easily activate a pay-per use mode to continue generating at the front of the queue.
If you reach the number of priority generations included in your plan you can easily keep generating with priority by entering your workspace settings > going to the plans tab > and clicking on 'Activate' to start generating on a pay-per-use basis.
You must de-activate the pay-per-use setting manually once you have turned it on.
The pay-per-use toggle is off by default and you will need Admin privileges on the workspace to activate and de-activate it
