Hi!
I foolishly skipped the A3 -> A4 migration step first time through, and now I've lost ALL SNIPPETS.
Per your web page advice, I deleted Alfred.alfredpreferences and prefs.json; this re-triggered the attempted migration, but "use sync" option was greyed out, and no matter how many times I repeat the process, my A3 snippets remain lost.
I have a snippets.alfdb file; how can I get my A3 snippets into A4?
