A couple of our users have loaded ArcGIS Pro 2.4.2 and are experiencing issues connecting to ArcSDE. ArcSDE is on a Postgresql database with PostGIS 2.4. One machine with ArcGIS Pro 2.4.2 locks up when making the connection and another shows no feature classes within the database when connected. The same database is accessed just fine with ArcGIS Pro 2.4.0 and ArcCatalog 10.6 and 10.7.
Does anyone else experience similar issues? What is the solution?
