I just needs some guidance as they say their notifications are on, they have checked their spam etc
This sounds odd indeed, I would recommend that you reach out to Pipedrive support so we can do a thorough investigation into this with you! You can reach out via in-app chat or via email at [email protected].
Typically we will request a screenshot of these users' sales assistant settings to ensure that the correct settings are enabled.
Sometimes we recommend turning the settings off --> save --> on --> save as well to see if that corrects the issue.
You can read more on these sales assistant notifications here! I hope this helps for the meantime!
