HRM connection to Lenovo P10

Has anyone managed to connect their htm to a Lenovo p10 tablet? I run zwift ok, but unable to get my Garmin dual hrm to connect in zwift (same problem when using wattbike app on the tablet). I have no problem in running zwift on Samsung s7 phone and hrm connects without any issue. I assume this must be problem in Lenovo p10 connecting with hrm via Bluetooth? Anyone with advice, or encountering same problem?
