Avast password - does not sync (mac) and on win 10 I can not activate sync

I have used avast pass on my iphone and mac. Worked well. Y-day my mac stopped syncing for no reason, it tries but fails. THEN i bought premium for a new Win10 computer and installed premium. Then installed passw manager too. BUT when i try to activate sync my logins fail. I have the correct passw, AND i even tried google login… nothing helps. I just get “Sorry, weve run into a problem. Please try again later.”…
AND I can not reach support… does avast actually have a person or chat?
