Account problems

can not log in to my account for days! what is the problem? new account works!

No issues here. Are you able to log into the companion app and the website, or is it just the zwift application you are having problems with? What device do you use?

i use zwift with the handy android system! with a 2 accout on the cell phone it works
I still have to test pc

the same on the pc :-/
