Hey,
I'm using a google sheet read row to trigger the workflow when i append a new rows, but it seems not work, i rename the sheet to default google naming "Sheet1" but still encounter not work, but whe i stopped thw workflow all the data i've appended to sheet appear in logs.
I had a similar problem with a excel on one drive so my question is simple (worked for me) where do you edit your sheet for testing. On your google drive (locally) or in the googledrive in your browser. Latter worked for me, the first didn’t do nothing at all. Maybe it helps.
Could you try removing the “Columns to Watch” temporarily and then execute the workflow to see if it works? This forces n8n to fire on any new row added.
