iWatch Cellular Activation Process MUST include information to TURN OFF iPhone VPN in settings otherwise setup WILL FAIL.

All service reps should know, and all regular contributors on here do know, that App Store VPN will mess up every device that Apple make, including set up, wifi connection, other App Store purchases... but I suspect the politics prevent official staff from saying so. They sell them after all.

The device is at more secrity risk with VPN installed because all your data passes through third party servers. I hope you know who owns them. Russians? Chinese?

I recommend you uninstall it, and remove the profile in Settings and leave it off. Same goes for so-called security or A/V apps.

You can make your feelings known to Apple, who are not here, to https://apple.com/feedback

You seem to not know you are not writing Apple here. You are only writing other users on this user to user only forum. Apple isn't here, so your request to make sure all reps are told, won't happen. And LD150 is correct, reps do know. Most veteran users here know. No iPhone, Apple Watch or iPad needs or really benefits in any way from using a VPN. In fact, using a VPN on one, can cause way more issues than they could possibly solve.

DUMP your VPN permanently. You don't need it.
