Are you running the latest version of the app? And are there any other apps running in the background when you play?
Is there a specific point at which the crashes occur (like, maybe when you’re coming in to land, or taxiing at a 3D airport or after a certain number of hours or something)? Or are they random crashes so far?
This happens to me occasionally but the main reason is because of either back-round apps, device over-heat and or the rendering and graphics qualities. I would clear the scenery cache and restart the device before you start any new flight.
Hmm, this seems like a case for Seb, aka schyllberg to check out.
It’s odd, because I remember there used to be a similar issue with the 777 a year ago in version 20.1 when the rework was done, but it was fixed at the time with a hotfix.
Usually a full reinstall of IF is the very last thing on the list to be recommended, but it may just be needed here, if the crashes are persistent. Anyway, you might want to back up your replays and keep them safe just in case you have to reinstall.
One more thing - how much free space do you have on your iPad? That might be a factor if there’s not enough free space…
