Mail is very slow downloading in iOS 18

My mail worked fast until IOS 18---now it takes forever to update on iPhone 14 pro max. When I say slow like 5 minutes to download, really terrible. I can go on my MacBook pro and boom it loads much faster. Told apple and was told no one else complained. Boo hoo---I am telling you the truth and this needs to addressed!!!

Same problem here.

I was suspecting my email servers but it seems to be iOS the problem.
