Somehow my 2020 declaration was recorded as I used assist and review which I didn't pay for. This year when I try to import my data to a new declaration and try to choose a version without assist and review I can't.
The buttons on the website are broken as no action are triggered. The problem is there in both French and English version. If I choose to continue with Assist and review everything works fine, it looks like it was assumed once you get assist and review you would never change version.
