In the Beta of this release, if a user encountered an issue where "Turn Ziti On" immediately flipped back to off. Do the following below and should resolve the issue.
1) From the ZDE lightening menu, select Logging/Level/INFO (even if it is already selected).
2) Turn Ziti On.
We believe that this is an artifact of the new TestFlight for macOS and will not happen when delivered from the App Store.
In addition, if the user want to set the Logging Level to something other than INFO, that should be no problem.
