I have an e280 with an 8G microSD card. Sometimes it takes quite a few tries to get the database to update after new CDs are added (and they are tagged). Sometimes newly added CDs get recognized after they are added and the db updated, and sometimes they don't. If I add a group, sometimes only some of them get found...and then more do after a few or many more tries. It seems to be a CD by CD issue. In some cases it seemed like it might not fully update...but after enough restarts and attempts to update, it did.
Does anyone know what might be happening here?
