I would appreciate some help with an issue that I've encountered recently.
I have two different free HubSpot portals, one which was created before the HubSpot upgrades, and one that was created afterwards.
For both of them I have created Apps, which have the same functioning principles: they create some Events (based on existing EventTypes) and update some Contacts information. The behaviour is the same up until a point for both portals, as everything is created correctly (according to the API calls).
The difference is obvious when clicking on a Contact for which an event was created. For the first portal, when I want to make a filter, I have no issues, as the Integrations tab is available, and I can choose my app. For the second one, things look completely different, as the Integrations tab is not available.
The problem is not just that I don't see the event in the Timeline of the user. In addition, when I want to create a workflow, the Events are not available as an option; it shows me that I do not have any events.
From where does this issue arise? Is it a matter of different configurations, or might it be something else?
Thank you for your help,
