when trying to sign-in to Lightroom Mobile (with iPhone 12) via Adobe-ID, it just shows an error. However, signing in with Apple or Google works just fine. I added a photo of the error below (it's german for "an error occured")
Can you offer some kind of support?
I'd really like to use the app as I'm going on vacation next week. 😞
I can't immediately reproduce any trouble sign-in. Could you try force-quitting and relaunching the app to see if that helps? Are you behind a strict firewall of some kind? Or can you try switching to another type of network, ie disable WiFi and sign in via cellular service?
