Two issues to report that are seemingly related to the March 2019 Desktop/Service updates.
1. I cannot add users to RLS groups in the service. This has been marked as a known issue but the resolution is not until the end of the month. That is just too late of a response for users who rely on RLS. The suggested refresh of the web browser does not actually resolve the issue.
2. Conditional formatting: I continue to lose conditional formatting for reports that were created prior to the March 2019 Power BI desktop update. When I try to reformat the conditional formatting it does not work.
