Dexcom g5 mobile weird stuff

Ok so I had stopped using this on my iPad but I had not deleted the app. It seemed closing the app had stopped the awful alerts etc. Then yesterday it suddenly alerted me 24 hours after a new sensor. When I clicked the alert button to stop it it says all alerts have been stopped now and I need to back into the settings to start them. I don’t want to completely delete the app yet in case I decide to try it again. Anyone else have these issues on your iPad?
