Pages site does not let me add custom domain

I have two domains registered in my cloudflare account, one of them was transferred to this account from a different cloudflare account via support. When I try to add the transferred domain to my cloudflare pages site it says I need to transfer my domain to cloudflare even though its already on cloudflare and registered under my account. This only happens with the domain that was transferred to this account, the other domain works fine.

Pro plan for multiple domains

I'm currently using Cloudflare's services for my personal domains for a long time now. The pro plan looks very appealing to me, but purchasing it for all domains in my account (around 10) would make this a very costly decision to make for something I do not gain any revenue with. Does Cloudflare offer any bulk pro plans so I can cover all my domains under one single subscription?

website unavailable on certain clients

Hi all, I have a domain name which I have recently moved to cloudflare from hostinger for DNS, and the server it is pointing to I am using on Zero trust tunnels for sub domains. Now when the domain was registered to Hostinger, there were no issues accessing the app, now that it’s with cloudflare, some clients globally are unable to access the app. It’s accessible from some clients and not from others. Is this is a known issue and are there any settings I can apply within cloudflare to correct this issue? Thanks all...
