Sound Core Flare is not connecting to iPhone SE

The speaker stopped connecting when I got a new iPhone SE. Tried to reset according directions by pressing both vol buttons simultaneously-no change. Also I noticed the power button is lit, but the bluetooth light blinks white when I first turn speaker on but then after a few minuets that light goes off.

bt enabled on this new phone?
Does the speaker show up at the bt list of that new phone?
Can you connect other bt devices to that new phone?
Can you connect the speaker to another device?
Sorry for that stupid suggestions but you know… :smiley:
