Thank you for posting those images. From what you've shown, it appears that you have found a bug. I have never seen the "Preparing first update..." screen you posted for more than an instant, nor have I ever seen the download status bar show red with no states showing red.
Before you try to fix the problem, I would request that you submit a bug report:
https://adventurepilot.community.fo...a-bug-report-from-within-the-ifly-efb-app.26/ . This will capture details of your situation that Adventure Pilot may use to troubleshoot what happened, potentially allowing them to improve the update logic so that your issue doesn't happen to others.
As for how to work around the problem and restore normal function, you may want to call Adventure Pilot during normal business hours and see if they have suggestions. Their phone number is available on their support page, here:
https://www.iflyefb.com/Support/Get-Help . (Note that they will be at Oshkosh next week and they usually close down the office for that.)
If you want to try to fix it yourself, you could try Menu > Check for Updates > Advanced Options, then check the "Force Database Refresh" box in the upper-right portion of the screen. Maybe deselect some of your states first, so that there's a smaller amount of data to download. If that fixes the problem, then you can subsequently add the other states back in and download their data, too.
If that doesn't resolve the issue, I'd rely on AP support for help.
