Following a suggestion in an earlier post, I installed the AppSheet add-on in Google Forms, and for a while this seemed to succeed in triggering a bot when a form was submitted, but now I find that it is no longer working.
When I submit a form, a row is added to the corresponding spreadsheet and to the AppSheet table, but the bot is not triggered. When I add a row through the AppSheet GUI, the bot is triggered. The bot is enabled.
With the caveat that I’ve not used the AppSheet-Forms integration and, so, don’t know whether what you’re observing is expected behavior, my next suggestion is that you may need to use External eventing with Google Sheets - AppSheet Help.
