Hey @La Dame Salon !

Kindly open your Google Sheet and Pabbly Connect account in Incognito mode and then try to add the extension and integrate it there.

It will work for you further without any issues.

Do check and let us know about it.

Hey @La Dame Salon !

Do you have an extension inside your Incognito mode?

If yes, then kindly remove the access once and then try to connect your Google Sheet to Pabbly Connect workflow and check if it works for you now or not.

Hope, to hear from you soon.
Hi Subin,

Thank you for getting back to me.

I had an extension inside my incognito and by removing the access if you meant to uninstall and install again so I have now uninstalled and installed the extension again but it still shows the same error 410


Any help would be highly appreciated.

Thank you so much

Hey @La Dame Salon

1. Please ensure that your workflow is switched on. If this is not the problem, then proceed to the next step.

2. Open your Google Sheets and Pabbly Connect account in an Incognito tab, and then try again.
