email does not load on wifi
Since I upgraded my phone to OS16, many emails will open only partially if I am on WiFi. I have three independent WiFi systems at my home, one on an Apple WiFi router, one on a Netgear Nighthawk Router, and one on a Comcast cable/WiFi system. The behavior of mail is similar on all of these. If I disable WFi while waiting for the mail content to load, it is instantly available as soon as I come back to the Mail app. This suggests that there is no problem with the Mail app, user accounts, passwords, etc.
Additionally, most email loads perfectly well. I have three email accounts set up on my phone, the native Mac account, Google mail, and a business account on a private server. The distinction appears to be whether the source is a distribution list or business account.
Other strange things are that exactly the same mails will load just fine on my M1 Airbook, which is up to date on OS and apps. I first had this issue on an iPhone 10, but the same problem continues on the iPhone 14 Pro Max that I just upgraded to.
In other words, this problem is tracking OS16 and little else.
Thoughts?
