I successfully created a database connection with Athena, and I can run SQL queries with it.
I was trying to use the Questions to test it but I don't know why tables are kind of unselectable; they appear in the dropdown button when picking up the starting data, but I can't select any table. You can see this problem in the first image attached.
I read that to enable this Questions capability I would have to Re-scan the tables that I wanted to query here:
I also tried to perform the connection to Athena from scratch, but when doing it I waited for 3 days to finish the sync and it didn't finished, so I cancelled it because it seems that it keeps syncing until infinite. So I stopped it by pressing "dissmiss sync spinner manually" and after that I synced manually with "Sync database schema now" and "Re-scan field values now".
Thanks a lot in advance for any help.
