Please help.

I have a pass on my mobile which ofc works fine on my Wifi. But when I go outside and it switches to data not only does the Pass not work, but I have to log out just to post at all even with captcha.

Then log back in every time I'm back on my home Wifi.

Is there something I can do about this? I'd be glad to buy a pass for different IPs but it seems I'd still have to log out and back in on another Pass etc.
