Ionic 5 and android 5,6,7

Hi, i just want to ask, whats the situation with runinng ionic apps on android 5,6 and 7 devices. Iam trying to run my app on android 6 and even on android 7 emulator, but it freezes at loading screen,
In console i get errors like this :

Uncaught SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode
Uncaught SyntaxError: Unexpected token =>

Are there any news on this topic? Is there some workoaround to support older android api? My ionic info looks like this:

@Vartex05 Have you solved this issue? I am also having a similar issue . My App stucks with white screen and error showing ‘Unexpected strict mode reserved word’

nothing helpful so far, still searching for some solution, so i can run ionic 5 apps on older androids version

@Vartex05 Thankyou for the reply
