Hello!
I think I found a bug. I created a sample to illustrate: Untitled document - Grist
Please open Form1 and enter URL in the form, e.g. “Baltic Amber Stone Magnet Souvenir Magnetic Natural Genuine Gemstone 5903 | eBay”. Then submit. The new row in Table1 will be created, but URL will be empty there.
PS: “Copy Link” button in Form1 does not work, at least in Safari.
