Lyft app on new Samsung Galaxy S22

Bought the new Galaxy and re-installed the Lyft app. I started using the app, accepted/completed a ride (the app worked fine) but needed to go off line. To close any app on the Galaxy, one simply swipes the app upwards, to close it. I confirmed the Lyft app was closed, but even though it appears the app is closed, I continued to receive ride requests. I couldn’t get the app to shut down. So had to delete it. I re-installed, but same problem happened again. Lyft tech support is clueless. They told me to ensure latest system software is installed (it is) and of course, re-installed the Lyft app. Does anyone have any suggestions?

By the way, I don’t have that problem using the Uber app on this smartphone.
