Folders Only Showing Read Only Key

[elevate]

1. When I go to get a key from a folder, what determines if it only has a "read only" key showing versus a "read / write" key also available?
2. I have one folder that only shows "read only" across all 3 machines ... how do I rectify that?

This is confusing since I just upgraded to 2.0.

In 1.4, I remember both key versions being there for all folders, so I'm not understanding the logic of the current setup.

Edit: solved the 3 read-only folders problem by re-adding the folder. I'm assuming these folder issues can crop up when upgrading from 1.4 -> version 2?

elevate, probably it has happened because those folders had keys, which not starting from A or B or another letters mentioned in this article.

For example instead of AL3YTINHLZM1324DU3DBQL5GX3SP4CTGH you might had 1593TINHLZM1324DU3DBQL5GX3SP4CTGH.
Such keys are obsolete and in Sync 2.x they will not work correctly. Sync changes those keys to read-only keys, something like this:

The only option to rectify it is to add the folder again with correct key.
