iOS 13 upgrade or app abandoned?

Is there a plan for an iOS 13 release. It appears the last release was a year ago. Greatest app and hope it sticks around.

This question also bugs me.
I have just made a yearly subscription renewal and I am seriously disappointed that the app runs so poorly under watch 6.1 and IOs 13.
Issues I am observing

  1. watch and iPhone kind of loose connection. This is no issue of the general connection between phone and watch because all other apps work well.
  2. Often the app does not start on the watch when starting a trace on the iPhone
  3. often the app on the watch does not stop when stoping the trache on the iPhone. I have then not found a way to stop the app other than powering off my watch.
