I have a Galaxy S9. The last update, perhaps it was Samsung, it is unreliable. When I put my hearing aids on in the morning only one of them connects. I have to force stop the app, clear the cache, turn Bluetooth off then on and try to connect. Makes me not want to use my hearing aids and I spent a fortune on them. UPDATE 2-20-22: This app is still not fixed. I have communicated by email several times and the only progress is in how much better I am getting with "work around" solutions with this app. I am wishing now that I had bought the cheap hearing aides at the checkout line at Walmart.
