fine for 2+ years.
A few days ago I noticed that the API calls from the web extensions are now failing and after debugging it I’ve found that the PSID is now an empty string in both the context object and the JWT (when decrypted), so our backend has no way to identify the user.
The bot is connected to the Page and the Web Extension is treated as an App in Facebook, they are both owned by the same FB Business account. The App has “Messenger” added as a Product.
Has something changed (silly question for FB I know)?
