I'm trying to install McAfee mobile security on a Samsung Galaxy Note 9 mobile (Android 8.1).
On first start, the app prompts for the email address and the 6-digit PIN.
It is impossible to proceed, because the email address is marked as invalid (with message "do not use special characters in the email address").
But there are no special characters in the email address - just letters! I already tried to follow http://service.mcafee.com/faqdocument.aspx?id=TS102650 (as suggested as reply to my post in Google Play) but this topic deals with a different problem.
Does anyone know a solution?
