Last week, there was an issue tagged in the 'Known Issues' section of the patch notes (screenshot attached). We have encountered this glitch and while I am working on a work-around I was hoping that it would be flat out fixed soon. I look today and I note that that line has been removed from the 'Known issues'. Has this already been fixed (perhaps on Apple's end? It seems related to upgrading to 14.2) If it hasn't been resolved why has it been removed from 'Known issues'? (EDIT: I stand corrected - I was looking in iOS known issues, not Unity known issues. It is still there) This was a major problem for us. We had an exhibition launch in Toronto and while things seemed fine during the week we tested the event, right after launch we had ALL kinds of problems with black screens ALL on iOS. Our clients reported having upgraded their phones to 14.2 during that week. Having seen this in the patch notes had me a little relieved, but I now see that has been removed. Our clients are NOT happy about this and it has been a huge hamper in our working relationship. Things were fine before the launch and then all of a sudden this was happening with no changes made to the app itself. Please advise on an ETA or a work-around I can do. I've already created a delay of 15 seconds between menu load and AR CAM scene-change so that if the user tries to go straight to the AR CAM from the menu (rather than browsing the menu) it'll create more of a delay to prevent rapid-switching.

Hi,
Hi,
Will ask the dev team for an update on this and update the thread.
Could you please also confirm which version of the SDK are you using?
Thank you.

I want to stress that this was working fine prior to mid-November (aside from my old iPad, which I'm not convinced is related). We have an exhibition in Toronto right now, partnered with Toronto Junction BIA. Shortly after exhibition launch, two of our main contacts with the BIA have

I have these errors reported on my Analytics (where I submit all Error messages thrown by the app) Are they relevant at all?
Hi,
Hi,
I've tested the app on an iphone 8 and I was able to reproduce the issue. In my tests I noticed that it works the first time afterwards switching to the menu and back to the AR scene results in a black screen.
It seems that closing and opening the app does the trick.
I am happy to try any hack
I am happy to try any hack that will get this working for our clients. Thank you. I will report the results after we get them to try it.
@mcotora - This doesn't seem
@mcotora - This doesn't seem to have helped much.
We have found a work-around
We have found a work-around that clears the issue. If you tap the home button to minimize the app and then pull it back up again the camera works fine. I wonder if there is a way for us to trigger the same effect in code.
Hi,
Hi,
Unfortunately I don't have any update from the dev team.
As next that we would recommend would be to share the Unity project with us to investigate further the issue.
Would this be possible?
Thank you.
