I have the same behavior on my H5 and I link it to the latest headset firmware update. I have a ticket opened with Beocare who was able to recreate the issue but they didn’t engage themselves in any plan for resolution, just a comment that it works for other products ....since IOS 12 sound settings are not saved. Power off the H8 will reset any sound settings which are previously set by the app back to default.
