My sky safary app begun to crash on startup yesterday night.
I've found that the problem is in some way related to the internet connection as I put my phone in airplane mode (no internet connection) the app doesn't crash. If I eanble the internet connection when the app is running there is no crash. The issue appear on startup with internet connection enabled.
Sky Safari plus ver. 5.4.0.0
Nexus 5 phone with Android 6.0.1
I've found a workaround disabling the cloud storage, saving the file locally solved this issue. Yuo have to backup your file manually of course.
