When making a new library in CC libraries and providing a new title, all of a sudden a colon (:) is now qualified as an INVALID CHARACTER! Since we have been working for years with libraries and have built up a file of hundreds coded with a colon in the titles - we experience a serious problem. We cannot change all titles to keep a logic order.
Apparently it is a cloud problem; uninstall & install the applications is no solution.
Can anyone tell WHY this bug suddenly appears?
How to solve?
