I have. I put in a ticket, but they're slow to reply, and I thought you might just know. No worries if you don't. Really appreciate your help.

Have a great day, and thanks again

Yes, the API key has nothing to do with LimeSurvey - how would we be expected to know?

Ofc, but I thought you maybe helped others who'd used the TINY plug-in. It was a long shot, but I thought it was worth asking, as you guys know so much!
