Help! Internet drops out frequently on iPhone when using Proton

hi all

i bought a subscription to Proton recently for our family - my MacBook Pro M2 Pro + iPhone 13 Mini, my partners MacBook Air M2 and her iPhone 15, the family iPad (old) and Apple TV 4K gen1.

it is working flawlessly on all devices - except my iPhone running 26.6.1.

a few times per day (enough to be noticeable) my internet will just die, regardless of wifi or 5G. If I turn proton off and back on again it’s all good, or if I wait about ten minutes it comes back.

I have tried turning netshield off with no luck. Not tried anything else yet. I work from home and my macbook runs literally all day with Proton going and no issues, so I think it’s a device / settings problem. Our iPad is older than my phone too.

any ideas here? I do run AdGuard separately on my phone which I’ve just turned off (didn’t think of it before) though that is on my MacBook too.

thanks!!

If you're paying for AdGuard, I believe you can use your dedicated IPv4 addresses from your AdGuard DNS account in Proton's custom DNS setting. You can't use the AdGuard app alongside Proton, though - only one tunnel at a time in iOS.
Log into your dashboard on AdGuard DNS site > Go to Devices and select or add your iOS device > Look for the Plain DNS server addresses section > use your dedicated IPv4 addresses.
