Tested this PR: Stopping the service and starting the app again with "Allow lower than limit" enabled now stays functional as expected.

I did happen to notice if you set the volume lower than the limit while stopping the service and restarting the app, the upper limit gets changed to that lower volume, meaning you'd have to go into the app and turn it back up if wanted. This could be considered a feature rather than a bug though depending who you ask since it could help prevent getting hit with overly-loud volume in some cases.
