There was a somewhat recent change to the intellisense (autocomplete) in expression builder in architect that now only looks ahead for variable names.
Ie previously if I typed Original it would find Call.CalledOriginal, now it won't I have to type Call.Call for example for it to show up. This makes it harder as you have to remember more precisely what each variable is in every single flow is called, ain't nobody got time for dat!
Yes on the upside typing 'or' doesn't search all variables with 'or' in it eg more, but honestly not worth the trade of.
I don't remember seeing this on announcements here, or in the release notes, was this announced anywhere???
