iOS BlinkUp SDK issue

Since updating the the latest iOS BlinkUp SDK I have noticed that randomly after the 1 2 3 countdown it will get stuck on a black screen for about 5-10 seconds and then the flashing will begin.

It’s random but has happened to me about 5 times over the last month or so.

Is this a known issue?

No, it’s not a known issue, and it’s not something I’ve seen myself.

What version of the SDK are you using? The current is 19.9.0, which uses our new enrollment API and so ought to be more responsive.

Yes we are using 19.9.0, it’s only something I have noticed since moving to 19.9.0.

Device is an iPhone SE. Running iOS 12.4

Thanks for checking the version. We’ll take a look at this.

Update, @jdelaune. From our iOS developer:

"I see this when debugging from Xcode, but have never seen it in a release (or even when detached from Xcode).

“My only thought is that they are possibly launching from a background thread rather than main which can cause issues like that. However, they will see a warning of this regardless as we don’t “follow” Apple’s guideline on this either as the BlinkUp is much more reliable when we use a background thread.”
