Is there a reasonable explanation why the new Pay app doesn't work with custom domain / business accounts? I am guessing it isn't resourcing.

The old one did; luckily I can still use that with my personal profile until I upgrade my phone, unluckily I didn't install it in time on my work profile - which is where I pay for many more things.

[Don't mean to bash on you personally, it doesn't sound like you are even on the app team, just annoyed by the downgrade.]
