And I wouldn’t since it’s still a closed source app.
I thought the issue was not being able to get the app, now it's the fact that it's not open source?
I really don't see why you are having so much Issues with a simple app
you can just remember the number
if you really want to make use of the app, get it through Aurora
if you don't want to use Aurora, create a burner Google account with an empty email address you only use for that purpose (I never had to give my phone number to Google, I have 5 accounts)
