Thinking of switching from ST: compatability

I'm using the [WITHDRAWN] NATIVE Broadlink RM/RM Pro/RM Mini/SP driver & RC HVAC Manager DevelopersCode Share and it generally works well.

However, one device perpetually fails to function after learning a code, and I'm attempting to use the RM Bridge with an RM3 to learn the code, but the link for using the app with an RM3 is not available, and it throws an error attempting to learn as an RM2

If it's not too much trouble please post how to use an RM3 with the RM Bridge. Update: was able to load this information on my Android device, failed in Win 10, Firefox

Upate2: got it all working by doing everything on my Android phone. However, the code fails when doing a Test. Same problem using Broadlink app, other devices work correctly.
