Installing Smartthings on Lenovo Tab M10 plus 3rd

Good find, I downloaded Samsung Connect and it works with Lenovo Tab P12 as well. But when updated to newer Smartthings app, it doesn’t work anymore. Something is changed inside newer Smartthings app, but what…?

Is it really so that in this forum, there are no one from Samsung side who is interested to give any feedback or support about this issue?
