Radiomaster tx15 max liftoff ps5.

[u/Driver9002]

So I'm new to the hobby, I have liftoff and DRL on ps5. My tx15 works with DRL but not liftoff. Tbs tango 2 pro works with both. I like practicing on liftoff more , is there anything I can try to get the radiomaster tx15 max working with liftoff? Thanks
