Stopped Pairing, No response from support – Halo Sport Review

Paired once with an iPhone XS Max running iOS 13.3.1 (latest currently) but now consistently refuses to pair. Have followed the instructions on Halo’s website with no luck. Tried deleting and reinstalling the app, reset network settings, hard reset of the phone. Nothing works. Emails to support have gone unanswered for a couple of days. Hoping support can help sort this out or will have to return the unit. Very disappointed.
