https://play.google.com/store/apps/details?id=de.gmx.mobile.android.mailHi,
regardless of in normal or HD mode
tested with Mozilla Firefox, Google Chrome latest versions and AirDroid 3.5.4 on Windows 10
So far I only encounter this bug with the GMX Mail App.
Probable reason: it uses a semi transparent GUI for the login screen when launched first time.
Reproducible
My sys specs see signature
PS: Teamviewer does transmit the GMX Mail App semi-transparent login screen correctly
Thank you for your feedback.
Would you please tell us more details of your question?
It would be helpful if you could send us a screenshot of the error page.
Feel free to let us know if you need further help.
Best Regards,
