Hi all, think I've got it working again. Tried everything I found on the Web. Deleting data in messages, both Samsung and Google, carrier services etc. Found a form to fill in on Google to deleted number for rich text services. Nothing worked, still chat services greyed out on Samsung messages with failed error message. Google messages kept asking for verification. In the end I disabled Google messages and just used Samsung messages without the rich text. However, I noticed in the secure folder, looking in the apps folder that both Samsung and Google messages were still there. So I disabled Google messages in the secure folder closed the secure folder and went back to Samsung message's . Surprisingly it allowed the setup and all is now working.
Must have been a conflict with the secure folder. It's worth a try. Hope it helps you guys. 😁
