Emplyes-Mustwashhands You don't need to keep Tor Browser and Cwtch on a separate profile from Orbot (though I recommend TorVPN over Orbot). Both TorVPN and Orbot check the app's name and, if they detect it's on the list of apps with native Tor support, they let that traffic through directly (without a VPN). This prevents Tor Browser traffic from passing through the Tor network twice.
If you only use Molly for texting, it has great Tor support. So you can also use it with Orbot.
btw: Vanadium supports .onion links, so you can access such a link directly from the default GOS browser instead of Tor Browser, which provides less security.
