Thank You,
I used the same fix before, and forgot about it! Even if Edited, one item, instead of Deleting it, or Creating a New Item, it would "remind" my macOS 10.14.3 about my Text Replacements! Logging Out and back in, and Restart would help too, but today it didn't! But, the Edited, Text Replacements would still work on iPhone, iOS 12.1.4!!! Then I tried your Steps 1-4, and it worked INSTANTLY on my Mac 10.14.3!!!
It's clear to me that this FEATURE, Text Replacements, is GREAT, when it works!
It is obviously connected to the iCloud, which is how it Syncs!
As I was Troubleshooting this issue today, I did look at https://www.apple.com/support/systemstatus/ and it was All Green = No Problem! So maybe there was a glitch there!
But even then, after seeing this Thread, it is obvious to me that Apple needs to improve this Feature, because I am not the only one having problems with it! Today, my Text Replacements in entire Letter B all did not work! Then your fix, Steps 1-4 Fixed it!
I also use this feature for Cyrillic Text Replacements, and some of them refuse to work! But, when I change the First Letter of the Trigger Text, it fixes it! Again, Apple needs to make sure that whatever Unicode etc. Table Translation is accurate in this Feature!
Ideally, I wish this Text Replacements Feature was as full featured as TextExpander, or close to it, that way there would be less Privacy Concerns, and no need for using TextExpander keyboard on iOS.
Again, THANK YOU for your Steps 1-4.
And Thanks in advance to Apple for your help!
