Unable to Connect Midi

Are Specdrums no longer compatible with anything other than the the Specdrum MIX and Specdrum EDU apps? No longer any midi compatibility, etc?

The product is advertised as being able to connect to other workstations etc. And there are videos of the product being used with Garageband and Abelton Live. Is this no longer a function? If so, why not?

And if it is, why do my devices disconnect immediately as soon as I leave either of the Specdrum apps? They are also not “discoverable” as bluetooth devices, which renders them entirely useless outside the Specdrum apps. This is wholly disappointing and also defeats the whole purpose I bought the product for in the first place
