Using the bang !fast on Firefox iOS just gives me an emtpy window

I have been having this issue the past 1-2 weeks, on iOS, using Firefox and Firefox Focus. I never had any problem before when using that workflow.

Steps to replicate:

Type a query + "!fast" in the browser search bar (in my screenshot below I typed "what is kagi !fast")

Result:

I expected the assistant to display an answer.

lou Can you show a video of this?

Actually I cannot reproduce this anymore! I guess we can close that one.
