Up2Stream Amp V4 Bluetooth connection issues

I have just bought 3x Up2Stream Amp V4, i already owned a Up2Stream Amp 2.1. I have a vinyl player from House of Marley: Sir it up - Wireless turntable, and this turntable can connect via BT to speakers or amplifiers that have a BT receiver. Now the issue, it does not want to connect to the Up2Stream Amp V4, but it does connect without any issues to the Up2Stream Amp 2.1 or any other BT speaker i own. I have tried all 3 of the Up2Stream Amp V4 also with the new firmware. But the turntable just does not want to connect to the Up2Stream Amp V4, can you guys provide any help. I find that even when i connect my Iphone 12 pro max to the Up2Stream Amp V4, it takes pretty long for it to connect while the Up2Stream Amp 2.1 connects almost instantly.
