Has Zoho Reports crashed?

I'm not able to open any of my reports, let alone work on them. I had yesterday written to Support requesting urgent attention but no reply so far. Today the situation seems to have deteriorated. There is not even an error message. All I see is the below (Generating Report...). Recent experiences have left me look for alternatives. Does anybody here have a first-hand experience with Microsot Power BI or Amazon QuickSight and tell how they compare.
