And so far at least I'm having problems with amethyst already installed on my phone. It's wanting to update amethyst like it's the same app and Obtainium doesn't recognize it as something different yet. At least I can install it in an alternate profile on graphene.

yeah it won't install an "older" version.
also
mine wants to sync the entire chain directly after creating the wallet.
setting a custom restore height only seems to prompt a resync from the beginning.
