AngeliqueTeo Yes, like Anonymous729 said, it’s WhatsApp. I mean, it’s happening with non-Nothing phones including a whole different OS (iOS, so iPhone), so Nothing can’t do much here.
You can root the phone though and get access that way but that’s up to you to decide if it’s worth the hassle (to potentially break banking stuff, like Google Wallet which refuses to work with rooted phone, and rooting then unrooting then rooting back just for WA, then unrooting… It’s a tedious process).
