Upgraded to IOS 11 & Text Replacement Not Syncing!

I experienced the exact same problem with iOS 11 on an iPhone 7. I found the solution in a different Apple Discussions thread for people who had experienced a similar problem after iOS 10 on an iPhone 6/6s. But it also works for iOS 11 & iPhone 7 as well.

Here’s how to fix it (I don’t know if each step is necessary, but I followed it step-by-step and it worked perfectly for me):

1. Go into Settings > General > Keyboard > Text Replacement

2. There shouldn’t be any text replacement shortcuts listed

3. Go back to Keyboard (I had all of the auto-switches for Auto-Capitalization, Auto-Correction, Check Spelling, etc. enabled)

4. Turn off Auto-Capitalization, Auto-Correction and "." Shortcut

5. Immediately turn off** your phone without leaving the page (**to clarify: turn your phone off does not mean reset your phone; you have actually manually turn off your phone off the right way)

6. Wait a minute or so before turning it back on

7. Open up Settings > General > Keyboard

8. Turn back on all the switches that you turned off in step 4

9. Wait a minute or so, and then go into Text Replacement, and all your previously saved ones should be there again

I did this and got all of my ~200 text replacements back!

Other things I tried before this:

• signing out/back in to iCloud multiple times - didn’t work
• adding/deleting new text replacements on the affected device - didn’t work
• adding/deleting new ones on my MacBook - didn’t work

Hope this helps!
