Connection issue with S7 Tab and Mi9 Lite

Guys - I am totally exhausted (more than after Passo Stelvio climb) with trying to connect Tacx Flow Smart with Zwift. My Android Galaxy Tab S7 and Xiaomi Mi9 Lite work perfect with Tacx app, but there is no way to connect with Zwift from the very beginning (Oct 2021). Any specific ideas? I tried everything… Airplane mode, turning off and on the Tacx, unpairing with Bluetooth. I don’t know what I can do. Connecting with Tacx app takes always 5-6 seconds, but Zwift? Sorry, Tacx Flow does not see.

Help, please. Thank you.
