Help choosing a headphone guitar amp

Hi all

Here is my use case - I want to get a headphone guitar amp for at home practice. Specifically to play along with Pickup Music on my computer.

I'm happy to control the amp either on my phone or my computer.

I recently bought a Spark NEO however when I connect the to the app for tone control on my android phone I cannot connect to my computer as well for Bluetooth audio (which you are supposed to be able to do).

Any and all suggestions welcome!

Thanks in advance
