Ok thanks Rich. I've submitted a bug report with the relatively limited amount of information I have / can provide.Appreciate the info on the StoreKit profile. I'll install it the profile on the devices I have here, in the hopes I can catch it at some point. I was actually able to recreate the issue the very first time it was reported, but was also where I discovered a restart would fix it, and haven't seen the issue / been able to recreate since...

Had a couple more users reach out this morning that they had issues subscribing.Both did not have multiple App Store accounts / changed their user name.One user had tried deleteing and reinstalling , but this didn't fix the problem.Restarting their phone fixed the issue in both instances (as it has in all other instances too).I should still stress, there are plenty of users who are able to succesfully subscribe the first time. It's just a certain percentage are getting an immediate error back from StoreKit that the transaction failed due to the 'Cannot connect to iTunes' error.I'm feeling this is really out of my hands in terms of what I can do to fix the issue, and it's really starting to have an impact on sales. Is feedback assistant an appropriate way to report this as a bug or should I be looking at a different avenue ?

I'll make sure to try and ask the next person who reaches out for support, but I'd guess likely *not* as there seems to be too many for that to be the case.. assuming that scenario is a bit of an edge case.
