I have an Acrobat Pro 2020 licence and a new Macbook Pro M1 Silicon. I can download the Acrobat program successfully, but during the first sign-in the licencing application window simply freezes and stays white. I have had help from two Adobe technicians who couldn't solve the problem - we know it isn't download, etc. related. I have also turned off all virus checkers, tried different browsers, reinstalled teh software countless times, etc. What else could I try? thanks!
