Since monday I have had issues with opening my dataflows. I just get the following error-message: I can refresh, but I can not access my dataflows and I can even see data in excel by connect...
typical Microsoft support unfortunately. i have at least one more open ticket where MS has confirmed a known issue, but it's not mentioned on the support page... really really poor support quality...
i also have a dataflow issue, but a different one:
it's only happening in MS Edge (in chrome things work)...
