Black Interface with no Data and import isuee

[MattFuks]

Hi,

first all - we need this app! Great work :)

Blackscreen in power app:

I've tryied to install the app as followed in your youtube video.

While importing it in power apps trough microsoft teams, it returns back this language issue:

I found a way, how to change and add these languages to a power app environemt in power apps admin center. But the problem is, that i can't change it on "microsoft teams"-types but on standard type:

Some have a solution?
