iOS 11 mail - manual fetch gone?

Solution 1:

I also use POP rather than IMAP and also for the same reasons, although my overall setup is a little different. That said, you should be able to still manually fetch your emails on iOS 11 as follows:

  1. Open Settings
  2. Tap on Accounts & Passwords
  3. Tap on Fetch New Data
  4. Ensure that the Push toggle at top is off
  5. Now at the bottom of the page, tap on Manually
