There is a new version of the Trimble Connect for Revit Add-In released today. Version identifier for this release is 1.60.1. The new version is available for download in the Connect apps store page for Revit versions:
Note the announcement: Mandatory update of all Trimble Connect for Revit Add-in installations earlier than v1.60.0 by September 1st, 2022
Does anyone have a copy of the latest installer for Revit 2019 v1.60.1 by chance? We have one project in our company still on Revit 2019 and they are stuck on v1.51.1. Any help is appreciated
