Hi,
Sorry, there have been no recent changes that would lead to these issues. They are situations where minor iOS or device changes can bring out new behavior so I would check against other iOS versions and file a radar if the behavior is undesirable, or spend more simplifying the messy code so a clear correlation emerges that would be possible to replicate and troubleshoot. I don’t actually support background mode so I wouldn’t be able to help much with that aspect generally, sorry.
I will close this since it is pretty far afield of the topic, but if you have issues happening in the foreground that you can create a reduced and simple example of an issue which is demonstrably related to OpenEars according to this process:

then it’s totally fine to open a new topic just for that report and I’ll be happy to take a look, thanks.
