UnknownProperty You mean the Whatsapp APK from the Play Store? I had that one installed initially from the Aurora Store, and it is the one that started with the crashes. Since then, I've tried the Website version... which still crashes. :/
And, I do use Signal! :D It's just that not everyone is on board, so I'm using Whatsapp for specific contacts. Though, I don't have much trust for Whatsapp - hence why I'd like to have it in a separate profile.
MetropleX Ahhhh, alright. Thanks for the explanation! I'm using the latest version listed on the Whatsapp website (at least, the latest version as of a few days ago... I didn't write down the version number when I downloaded it). The website lists the latest version number as 188.8.131.52, so I imagine mine is just a few days behind that one. If it's the case that they're using an outdated interface, then I imagine there's not much I can do on my end? It's odd though, as when I asked this question in the Matrix room, it seemed that others were able to run it just fine in secondary profiles. Could this be device specific? Pixel 4 vs Pixel 5, for example?
