Google Messages 'Chat Features' setting up indefinitely

[Supra]

I have Version A (According to Gearbest) on Vodafone UK and I haven't been able to get chat features aka RCS working. Tried clearing storage and hitting that Retry button when it's available but nothing. Latest .174 update.

Did you manage to get this to work? If not, then I can ask our developers if they know why and it there's anything we can do

Just wanna update you that with the WW_16.1220.1909.193_0 build chat features work now.

It's not a ZenFone 6 bug, it's an Messages.apk bug and it's on since I remember, for many many years.
I've had this issue since my first OnePlus One! 🙂

I've managed to get it work by puting a second sim card (borrow from family or friend). Then, reboot the phone and activate the RCS (Chat Features) on the first sim card.
After it's done, you can take off the second sim card.

Hope it helps!
