Just wanted to know if any issue or regression with with April 2019 CU / May 2019 CU for SharePoint 2013 ?
Has anyone experience nay
There is no issue with April 2019 CU and May 2019 CU for sharepoint 2013 in the official documents.
Then we recommend that you test those hotfixes before you deploy them in a production environment.
There is one issue that we encountered .
The word automation service application stopped working after we applied this CU .
Tried this for both the SharePoint 2013 as well as SharePoint 2016 farms.
The issue is that the CU revokes the permission of the service account running the application pool of the Word automation service application .
So after you have patched your environment make sure you have given the permission back again and try once if your word automation service application is able to convert documents to pdf's.
I will keep you updated on more issues as I keep finding them .
Just to sharing my experience.
I installed April 2019 updates on SharePoint 2013.
There is no issue with the CU.
Everything is fine after upgrade.
