Hi,
@DD2207 , another possibility might be that your phone's OS has updated recently?
I've been getting a few 'reminders" recently to upgrade to a newer OS, but I've always ignored them because I've seen too many posts from folks finding that upgrades messes with xDrip+. I'm still running android v7. V9 caused lots of problems.
It's sometimes worth having a look through the open and closed issues page at link below. The xdrip developer, JamOrHam, and his team contribute to it, and take note of issues with a view to fixing them, so it's like top level stuff.
