Dear Microsoft Support,

We are encountering an issue with the Insert Dynamic Text functionality in Dynamics 365 CE 9.1 On-Premise (UCI) after upgrading our environment to v 9.1.45.11.

Prior to the upgrade, the Insert Dynamic Text feature was functioning as expected. After upgrading to 9.1.45.11, the feature no longer works. Looks like a new rich text box controlled loaded after upgrading to v 9.1.45.11, and it is not working properly.

Issue Description:

  • Open an Email Template in the Unified Client Interface (UCI) from Dynamics 365 CE 9.1.45.11.
  • Click Insert Dynamic Text.
  • No dialog or Dynamic Text selection window appears, and there is no response in the UI. The feature appears to do nothing.

While checking the browser developer tools, we observed the following errors:

  • HTTP 500 Internal Server Error when loading a required resource.
  • CKEditor error: editor-plugin-required

Could you please confirm whether this is a known issue in Dynamics 365 CE 9.1.45.11 and advise if there is a hotfix or workaround available?
