Sometimes a simple Restart helps to solve problems. Try it.
If not, let’s clean-up and remove all preferences files:
Close Netmo (maybe you need to kill Netmo via the
Activity Monitor)
- Open Finder
- Press and hold "Alt" and choose "Go" and „Library“ from the menubar
- Open folder "Containers"
- Delete the folder
„at.agross.netmo“ OR the folder
"Netmo" (on macOS Big Sur)
-
Important: Restart your Mac!
- Start Netmo again.
Here are some screenshots that explain how to delete the settings folder of Netmo (or any other app installed on your Mac).
