Thanks for the info.
Here is an interesting way to get a Glide app to play an audio file in the background on an iPhone. I did test this by downloading the Dolphin browser and following the instructions in the article. https://www.macworld.co.uk/how-to/iphone/play-youtube-audio-background-iphone-3509461/ I was able to work on other apps and go into screen lock on my iPhone, so it works at least with my Glide app. @Thomas_Dahm, give it a test yourself to see if it works for you.
Yes it does require some steps that a novice user may not be capable of. Also this browser does not have an “Add to Home screen” option so you have to run the Glide app inside the Dolphin browser for this to work. It won’t work in Safari or Chrome. Also the Dolphin browser doesn’t have great reviews on the iPhone and it crashed when I tried to open a second tab.
@Mark @Jason @david Apparently there is something about Dolphin that allows background audio to continue to play on iPhones. Maybe it’s worth a lunch break meeting with them to discuss why and see if it is something that could work for you??? They are in your neighborhood.

EDIT: I just tried the same process with a Home Screen installed Glide app and it is now playing in screen lock mode on my iPhone. No Dolphin browser.
