I found an answer...at least partial. There is a suggestion that one needs to clear the Cache. C:\users\your~username\AppData\Local\Tableau\Caching\ExternalCacheV1\MapTiles
that worked! although it is a hassle.
Yes, you do need to clear the cache as described above. This is something that we are considering adding a UI entry for in Tableau in a future release, so thank you for the feedback here. Can you elaborate a bit more on the part where you indicated it took a couple of hundred hours. Was that because the Map tiles needed to process before you could use the map in Tableau?
I'm a slow learner! And an impatient one so I kept trying things without reading all the info first!

This worked for me too, a year later with Tableau 10.4!
