Bluetooth Soundcore Life P2 no longer plays with both ear pods

My Soundcore Life P2 suddenly quit playing using both ear-pods. They pair as expected using Bluetooth but sound only comes out of 1 EarPod at a time. Normally I would expect this to be a hardware related problem but this started after upgrading to an iOS 15.6 update on my iPhone 7-plus. I found nothing on Soundcore’s help site.

suggestions?
