Hi,
We have identified this issue and are currently working on a fix. It will be available in the next update 8.23.1, but as we need to wait for Apple’s review (which can take 24-48 hours) we recommend those affected by this to use the web app charts.navigraph.com in Safari on your iPad in the meanwhile.
Sorry for the inconvenience caused.
Regards,
Stephen
Thanks for responding so quickly.
Update - I am still having CTD issues with the latest version 8.23.1. Just downloaded the updated version, logged in, and then it crashed. Open the app again, it crashed. Tried a third time, it crashed. Is there a rogue bit of code lurking somewhere because I haven’t done anything to my iPad OS (16.3.1) as the app was working fine before these latest updates.
Is there any chance of being able to download an earlier, stable version for IOS?
Dang, How I hate to be inconvenienced by a snag in an update to an amazingly awesome free app. 
grateful! Thanks.
I hope update will be out soon because the app is totally useless due to freezes and crashes. I am on iPad Pro 11" 4th generation iPadOS 16.3.1 for your information. Thanks and best regards
Hello everyone! We believe that we have a fix since we are no longer able to reproduce this. We will now submit a new version (8.23.1) to Apple, but as @stephen has already mentioned it won’t be immediately available due to their rigorous review process.
Thank you for your patience so far, and sorry for the inconvenience!
Good news! We were able to get an expedited review process and the app has now been released.
Please try out the new update and let us know how it works out!
Kind Regards,
Malte
Seems to work normally again, crossing fingers it will remain stable.
Thanks!
Hello,
just came across this thread after expericing the same issue with the app crashing / freezing and found this article on my iPad gen 9 with iOS 16.1.1 (20B101)
Updated the app to V8.23.1 build 1 and it’s no longer freezing / crashing as before.
Thank you for the reports guys! We’re happy to hear that the situation seems to have improved.
Please keep 'em coming, good or bad!
Kind Regards,
Malte
the new version seems stable so far, however, I noticed that the simlink app is still intel only code. Not sure why that is but seems odd that a universal plug-in would require an intel only app to communicate with an iPad ARM app. And why would I need to run rosetta in the background just for simlink. That just doesn’t make sense to me.
Thank you for the feedback! It is much appreciated!
Regarding Simlink, let’s keep the discussion in this thread:
I have tried this for a few flights and seems much better indeed.
Many Thanks
Hey There!
I still have issues on iPad M1 Pro, 16.3.1 with v8.23.1 build 1 - still freezing on loading charts on an import of simbrief, if simulator is open and simlink is connected. Clicking on the pinboard and switching throgh charts is leading into crash/freeze of app.
