iPhone won't redirect to login to public WiFi networks. Works fine with private networks

I got the iPhone 15 pro max last week and ever since I haven't been able to access public WiFi networks where you have to "login" or agree to terms & conditions (i.e. Shopping centers, mall, etc.). I tried switching off the Auto Login toggle a few of times and resetting the phones network settings to default but that hadn't worked. I have compared the phone to another that does work and I can't locate the problem.
