All of the sudden (perhaps after the April 2017 update?), any dashboards we share out-of-tenant from Power BI Web are missing the tabs along the bottom to switch between the different reports in that dashboard.
We tested with in-tenant sharing and it works fine - only an issue when shared externally.
We tried creating a new dashboard from scratch with 2 simple tabs and published out of tenant - same issue. All tabs are just gone!
There seems to be other issues with PBI of late (data failed to load when first opening a dashboard) so perhaps the tabs missing are part of a bigger problem. However, for now that is the problem that is getting in the way of us delivering analytics to our clients.
Any help would be greatly appreciated!
P.S. We had another issue with out-of-tenant dashboards where the Export Data just didn't work for them. It was eventually fixed, but I'm beginning to wonder whether or not out-of-tenant sharing is the red-headed-stepchild of the PBI feature set. It could certainly use a little more testing with each release...while I love the pace of innovation of PBI this isn't the first time that something in this dark, scary corner of PBI was broken and our clients were impacted. Food for thought if this post happens to cross into any PBI QA LOS.
