Not sure if archiving will help since it just hides the experience from you but not from the system. Also, archiving them will just make them useless. In my case I have about 50-70 experiences, including public, private, and archived, and I can’t archive all of them because I need them.
Honestly, I just hope nothing happens, as 20% of my experiences don’t have the questionnaire updated, and 60% don’t even have it…
Good luck to all developers.
