After upgrading from vRO 6.0.0 to 6.0.1 I tried to share some Dashboard tabs and templates with certain account groups.
I have multiple solutions added which creates a lot of dashboards so when viewing the dashboard window under content i see all 69. However trying to share dashboard only a count of 50 is displayed so cannot select all dashboards.
I opened case with VMware support and they were able to reproduce the issue where the dashboards shared window cannot display more than 50 entries.
Fix will be available with next release.
