I am not sure why, I used CloudDB2 for some screens, CloudDB1 for some screen (basically duplicate CloudDB) but when I wanted to retrieve info from CloudDB on one screen I couldn't get any until I found out that I had to add another CloudDB (which is CloudDB2) to finally retrieve info. Why is there a difference? Don't they use the same ports key ID and stuff.
Any instance of CloudDB you drag on to your project, regardless of which screen you drag it on to, should have the same token, and therefore relate to the same instance of CloudDB. Thus, a tag you store with "CloudDB1" is available as the same tag on another screen in another instance of cloudDB, e.g. CloudDB2. Hence, there is little point dragging out an additional instance of CloudDB to any screen...
This is what happens when I change from CloudDB1 to CloudDB2
