Sorry to report.
Just installed Skysafari pro v 6.6.4.10, running on Ipad pro 11" , IOS v 13.1.3,
Equipment Celestron CGX mount, Skyportal 3rd generation WiFi module,
With Nexstar+ HC or Starsense hand control
Ipad Pro 11”, IOS v 13.3.1
-----------------------
I connect Ipad to Celestron WiFi, then run Skysafari Pro., connect to Celestron WiFi.
In SkySafari Pro , under Settings, GRID & REFERENCE, Reference lines,
I toggle MERIDIAN LINE ON., click Done
Meridian Line appears on screen.
I then Swipe up on ipad, go to another app. (Skysafari disconnects WIFI)
Return to Pro
Pro auto reconnects to Celestron Scope WiFi
MERIDIAN LINE is no longer visible. When I look under settings, MERIDIAN LINE is OFF
ALL other REFERENCE LINES remain enabled/displayed when I switch focus from Skysafari app to another app and back.
ALSO:
If I use the DISCONNECT in Pro, then CONNECT, the MERIDIAN LINE remains ON.
If I DISCONNECT in PRO, then switch apps , connect to a new APP, then Return to Pro
and CONNECT in Pro, the MERIDIAN LINE stays ON.
Let me know if you have any questions.
Take care
Steve
