Byron,
Love the app! The recent 15.4.1 iOS somehow spit out an error that doesn’t fold the settings like dispensation and mode when opening and reclining the app. I use your all nearly every day. Please help! Thanks so much. Tried reporting via AppStore button and didn’t have any luck reaching you.
Cheers!!!
