App switcher on Apple Watch

I am using the Apple Watch, SE2, and for the most part it is great. However, there is an app that seems to be having problems. It's the Dexcom G7 app. I have "direct to watch" turned on in the iPhone app, and the watch did pair with my sensor successfully. However, over the last day or so, it has started throwing up frequent alerts about how the connection was lost, so it goes back to pulling data from the phone. Really, it doesn't matter that it is the Dexcom app. It could have been any app really. The problem is, I wanted to go in to the app switcher to close said app, and then go in and open it again. The problem is that the app switcher won't stay in place long enough for me to actually do anything with it. It flips from the app switcher in to whatever I happen to be focused on, or one of the other apps in the list. It's driving me nuts, as I have tried it like 15 times, and each time, before I can find the Dexcom app, then flick up to get to close, it jumps back in to another open app before I can actually do anything. I have looked in settings to see if I could find anything that would cause the behavior, but nothing stands out. Hoping someone smarter than me, or at least more experienced, has figured out a way to solve this. Like I said, it really shouldn't matter which app it is. The app switcher should not behave like that.
