I have the same problem as you did months ago. I just added emojis, today, March 13, 2018. Did you ever figure out a fix for this in your troubleshooting?
If I turn the retort limited emoji set off I get this cut off window which you cannot scroll down:
If I can just get my tailored list of emojis to work, I’m happy. Looks like it should work fine if go by this rule (Thanks, @gdpelican.):
Except I have 25 emojis but they aren’t forming 5X5 rows. Any ideas as to why this might be?
I can get 20 icons to work though, but then, the last emoji doesn’t appear and only a clip is displayed instead of an image If I do 20 emojis:
Should I be using this forked version, @schungx if I want to have neat rows, not be limited to a particular number of emojis, and fix the defect in the last (bottom-right) emoji that is invisible?
