Hello, I think I have been having the same issue. When the webhook sends data to Google Sheets in 30 percent of cases, after hitting form submit button, the wheel keeps spinning forever. Where can I paste the code with the filter?
After numerous attempts I finally gave up and installed Contact Form 7 with the upload button working great! In comparison with Easy Contact form the CF7 is much more managable and user-friendly (even though it seems less customizable) – it took me 5 minutes to create a contact form I spent entire day creating in CF7. Recommend to all of you!
