Today I found out that Hubspot will automatically disconnect social media accounts every year. With this disconnection, all history on monitoring is gone and reporting is only available for the last 60 days. Since I wasn't aware of this, I did not create back-up reports to save the prior information.
Recommendation: Store social media information somewhere as back-up, so it remains available for a longer period of time. And 2nd recommendation: sent a notification prior to the disconnection. This enables the user to save information and let's him know that the disconnection is coming (so that there is no confusion when the account is 'missing'in hubspot).
