Thanks so much for the info - yikes! Its as bad as we thought, they really put you through it. My husband read your response and said: that’s as much trouble as they put us through getting a French bank account. Unfortunately, we just own property in France, our principal residence is the U.S. We’re retired, so no job or commercial reason to be in France, no French family (just a lot of friends and neighbors that we miss), and certainly not students, which means that until they lift the requirement for the attestation (or change it to allow those of us that own property) we can’t come in 
We are normally at our house there 3 times a year, and now haven’t been back since mid-March. Its really causing us heartache.
Thanks again for the thorough explanation - we were debating looking at flights, hoping for a change soon, but I think we will hold off 
Enjoy your time in Paris, I’m completely envious!
