Yesterday and today, I keep getting Cloudflare pop-ups saying something about my kids’ school district web site. It’s constant. Thing is I never signed up for cloudflare, so why is this on my phone? I check settings > vpn, there is nothing listed.

Certificate SSL ssl761578.cloudflaressl.com - not trusted, expired 10=13=20. Issued by Comodo ECC Domain Validation.

​

When I look at details, it says that it’s from Great Britain, Salford.

Please help.
