I have been adding snippets for a while. No problem.
I tried adding a few more. Also tried by a "copy" of one that was working.
I input the information, then hit "TRY OUD" : I put in the shortcut starting with the / - I hear the noise but the "Label" doesn't show up - and it remains block. Won't work in any other area either. So I have my current snippets, working fine, but can't make any new ones.
Hope someone can help.
Much appreciated. (that was a snippet, I created - working fine).
Hi @Ccgreen Welcome to the forum! 
- Does this issue only affect longer snippets?
