on April 23 i used Sky Safari Plus (iPadOS) for the first time to control my Celestron NexStar 6se, and all worked fine right from the start.
we then had rain for weeks, and on May 11 i tried to use it but after many failed alignment attempts i gave up. i should note that i was using the reticle in ASIStudio with my ASI294mc, these alignment fails were NOT me. yes, the time & date, etc were right, of course i checked those. i continued that night using the hated hand controller on the scope to align.
last night, May 13, Sky Safari wouldn't even connect; it gave the Connection Failure dialog box multiple times, even after completely powering off the scope and quitting/restarting the app. i then immediately started up Celestron Sky Portal and it not only connected, but alignment was perfect the first time (even though i did a quick and sloppy alignment). i tried again this morning to connect via Sky Safari Plus on both iPad Pro and iPhone 12 mini, with Connection Failure again. again, Sky Portal connected right away.
i note that between those 2 uses, on May 12, the app was updated on the App Store.
