Button connected but no messages received

[arlomedia]

I have a couple users with a first-generation Flic button who are reporting that my app receives no messages from the buttons. Here's what I know:

• Users are clicking a button in my app that calls [[SCLFlicManager sharedManager] grabFlicFromFlicAppWithCallbackUrlScheme:@"[appscheme]"]. This goes to the Flic app, which shows the button, which they click and then click Done to return to my app, as expected.
• My app is calling [[SCLFlicManager sharedManager] knownButtons] and that shows that the button is connected.
• Users click the Flic button, and they hear the Flic app beeping to indicate it is receiving the message.
• My app's didReceiveButtonClick method is NOT called.

This works fine with my Flic button, on an iPhone or iPad with iOS 13.3. Both these users have iOS 13.3. One user says that he has a different device with iOS 12 and the button works as expected there.

I did find a problem where I was checking for an error in didGrabFlicButton and returning, and setting button.triggerBehavior after that. So a button that was already known to the device, but which somehow forgot its triggerBehavior setting, would trigger didReceiveButtonClick and didReceiveButtonHold but not didReceiveButtonDoubleClick. Is there a default triggerBehavior setting that would cause it to not trigger any of these methods?

Otherwise, is there anything else I can check to find out what's wrong? (I don't have access to the devices to debug with.)

Based on this documentation, it doesn't look like a bad triggerBehavior setting could be the problem: https://partners.flic.io/partners/developers/documentation/ios/Constants/SCLFlicButtonTriggerBehavior.html

I've more than one paired Flic buttons in my app. I left my app in background(not killed) for 4-5 hours and then I click single/double even more than one time on Flic 1.0 button then it shows me red light in it means it shows disconnected in device bluetooth settings as well as after opening the App in foreground. It shows me red light in Foreground also. It happens every time. If I restart device bluetooth, it continues working means shows connected in device bluetooth settings.

It is missing "Single Click", "Double Click" and "Press and Hold" triggers. So my working is stopping on this situation. Please have a look on it. I'm working on iOS 13.x.

Please give me a stable solution for it if possible.
