I have 9.2.4 installed on a RPi3. When I create two additional profiles (we are two people living in the same household) and then set Kodi to show a login screen at the beginning, if I choose one of the two newly created profiles nothing happens. It remains on the login screen. I can then log in via the Master User and switch users via Settings --> Profile. However, I can then e.g. only choose ENGLISH as language. It is connected via Internet but the "more" option doesn't show. Also under the Settings "LibreElec" doesn't open but it wants me to wait until it is loaded...
I tried setting up the two profiles today from scratch since yesterday, on a fully running Kodi instance, adding the two profiles later has led to a constant reboot of my RPi3 after the Leia 18.8 screen popped up which lead to it starting in safe mode.
