Do you have the same issue if you follow the OP’s steps to reproduce it?
The loading bar gets stuck around 75%, sometimes it keeps loading very slowly until the end, then it doesn’t load
Provide extra information to complete the original description of the issue:
I noticed that when I disable online access it does work.
What I don’t get is that it worked perfectly and then between two flights it started acting up. No changes were made
