This past weekend, i set up the AM5 with the ASIAIR plus to do some solar imaging. i used my Samsung S22 ultra with the ASIAIR plus to move the mount to face the sun. In the ASIAIR Plus APP, I did not see any down arrow. All other direction arrows were visible. I am using ASIAIR 2.0. I had to use the AM5 mount to slew so it wasn't a huge issue, but what happened? We've had some lousy weather preventing me from setting up again. I may try a ipad to see if the issue is with that device.
