Call & Text on other devices setup

[Sam162]

Hi, hope someone can help me please I? have the Samsung S20 Ultra and the Samsung S6 Tab, but for some reason I cannot connect the both to set up The Call & Text. I have signed in on the same account for both the phone and tab. The only phone that keeps coming up on my Tab is the S10 Plus, which I no longer have! Can someone please advise me on what to do? It's driving me insane! Thankyou

Hi , go into calls and texts setting on Tab S6 , hit the 3 dots in the top corner and there's now a link this tablet to your phone which brings up a QR code to scan with your phone

When I scan the QR code (from Galaxy Tab) on Galaxy S8 -- It opens Samsung Notes and pastes the "cmc://" URL in there. I uninstalled Samsung Notes, and now an app chooser comes up with ~20 apps. What do I do with this freaking thing? Which app is supposed to handle this URL and link my tablet with the phone???
