Thanks for sharing! Not sure if you found it but in response to MattSchultz2 I wrote an update with a possible temp solution to this problem. I’ll copy it here for you:
Update: So I went & had several screenshares with 2 of Apple’s tech support agents about this #images problem. On the second session, we found that unfortunately for now, it-is-what-it-is. There is one work around until Apple’s engineers work out a solution in a future update. Since the technical advisors found this issue so interesting, I am hopeful that Apple will resolve this in 13.1.4 or next update. The workaround that we found didn’t involve resetting all network settings or deleting all content and settings, nor does it require a reload of the operating system. Instead of all that craziness and time wasted, you do have the option to go to the App Store. From there, look for an actual third party keyboard & install it. This will allow you to access and search for memes and “#images” like before but through the use of the alternate keyboard, instead of Apple’s faulty one, presently. That’s the best I can offer everyone as a temporary fix until Apple figures out a better, more streamlined and user-friendly solution. I mean let’s be real here, that little red icon on our regular keyboard is an every day reminder that we can’t use the app for what it is designed for!
Let’s get it done Apple.
