I didn’t sufficiently clarify my 2nd question.
By “test the mobile device” I meant ANY User’s mobile device – iPhone, Android, iPad, etc.
If a Wappler developer suspects or knows that there are liable to be some systemic incompatabilities that may prevent a particular User’s iPhone model, for example, to install the wappler app with full functionality, as the developer intended.
Besides all the regular app simulators & testing software bugs, etc that a Wappler developer does to insure his/her app is passing all tests. – are there situations where a Wappler developer of a mobile app might want to give the new User a pre-install “device system test”?
