It works perfectly fine when launching using am start with package/activity
I have currently a kiosk-like functionality working by using the android manifest to request launcher.
This only occurs using config.txt with the same PUI version as you say
Could you show me a sample of a working config.txt for unreal application? :)
Our project is very old, perhaps there are some changes that we have to do to make it compatible? The project has been upgraded all the way from 4.19 to 4.26 over the past.
