Tesla S 2017 live data connection failed

I use this app (current 7.1) since the very beginning. Live data connection worked fine (last year). Currently I‘m not able to connect my Tesla S 2017 with the ABRP (iPhone, v 26.6.1) app. When klicking in connect, it opens the Tesla site, I enter my credentials and get the message that I‘m fine. Then it links me to the ABRP website and asks to log in. All works fine, but still no live data. Also the iPhone app doesn‘t show live data. Any advice?

Thanks, Joe
