Live Link Face and Tentacle Device, how?

Hi, After a long wait on backorder we received our Tentacle Sync devices. These are working well everywhere except for Live Link Face. LLF always says NO DEVICE. Phone has bluetooth on and the devices are seen in the ios Tentacle app. Using the app I can sync all devices via Bluetooth but devices or TC is not seen by LLF app. The LLF app has bluetooth permissions granted. I’ve also tried different rates and cables with no change. Is there any clues from someone who has got this to work? Have I got V2 devices and it only works with V1 or something? Any help would be appreciated
