AI Generate Text workflow not running/no output despite correct setup

Hi everyone 👋
I’m hoping someone (or Glide staff) can sanity-check this, as I feel I’ve exhausted all standard debugging paths.

What I’m building
An AI-powered resale listing generator (Vinted-style) using Generate Text in a workflow.

Setup (confirmed):
• Data table: Listings v2
• Input columns: Item Name, Brand, Colour, Size, Condition, Notes (all basic text columns)
• AI prompt stored in a basic text column (Prompt (Text))
• AI output written to a basic text column (AI Output Raw (text))
• Downstream fields (Title / Description / Price / Hashtags) extracted using Extract Matching Text
• Workflow trigger: App Interaction (This item)
• Condition: Needs AI = true and AI Locked = false
• Button in the app runs the workflow for This item
• All regex patterns tested and valid
• No computed/template columns used in AI input or output

Issue:
• Workflow does not run (Run button greyed out unless triggered in app)
• Triggering from the app produces no AI output
• No errors shown
• AI Output Raw (text) remains empty
• Downstream Extract Matching Text columns never populate

Things I’ve already tried:
• Rebuilding workflow from scratch
• Simplifying prompt to plain text
• Removing regex entirely
• Writing AI output directly to a visible column
• Verifying Needs AI / AI Locked toggles
• Testing on multiple rows
• Testing on mobile + desktop

At this point I’m unsure whether:
• There’s a limitation/bug with Generate Text + App Interaction
• There’s a hidden requirement I’m missing
• Or whether this is simply not reliable for multi-field AI generation

Has anyone successfully shipped something similar recently, or can a Glide team member confirm the expected pattern here?

Happy to share screenshots or a clone if useful.
Thanks in advance 🙏
