Hello Community,
I’m looking for insights into the @mention feature in model-driven app notes.
We’ve been trying to utilize the @mention functionality in our model-driven app’s notes section and have enabled/disabled all related features in the Power Platform Admin Center (PPAC) as follows:
-
Enabled the Monthly Channel.
-
Activated the @mention feature under Collaboration (
Enable @mention feature→ Save). -
Turned on In-App Notifications in the app’s settings.
-
Disabled the modern rich text editor for notes.
Despite these configurations, the feature isn’t working. After reviewing our setup, I realized that when creating our environment, we overlooked enabling the Dynamics App, which appears to be a prerequisite for using certain features.
This brings me to my question:
Are there any options to enable the Dynamics App in an existing environment? If not, what alternatives exist for implementing the @mention feature—perhaps using JavaScript or custom code?
For reference, we raised a support ticket with Microsoft over 35 days ago but haven’t received much assistance. Creating a new environment isn’t viable since this is a well-established production setup.
Any guidance would be greatly appreciated!
