I have not used the camera adaptor but I'm able to use a Lightning to Micro B adaptor with no problem on my iPhone SE.
may I ask if GO V2+ still works with lightning adapter (MD821AM) on the latest iOS (11+)?
My old DIY lighting to usb cable no longer works after the iOS update; I hope MD821AM would work on latest iOS...
I have checked some resources and it looks like this update has affected all lightning adapters including Apple's. Apple has not made any statement and there are a lot of finger pointing and rumors as to who or what is to blame due to the fact that in some instances the adapters have worked. I personally use a lightning to micro B adapter I purchased and when I get the nuisance notice that 11 no longer supports I tap OK and then detach and re-insert my adapter to get it to work again. It's a pain but until a fix comes through there are not many options at this time. Hope this helps.
You are welcome. Some have not had any problems, so glad to hear. Thank you.
