Deleting Completed collections

Hey Player043822707! Check out the steps
here for info on how to remove them. Thanks!

I WOULD LIKE TO DELETE AT LEAST 50 COLLECTIONS EHAT HAVE BEEN COMPLETED . PLEASE HELP ME DELETE SOME , THANK YOU

Although I haven't run into your exact problem yet, I have had a problem with downloaded collections: I've completed all the Cityscapes (one of the two free downloadable collections, Food being the other) puzzles on both easy and medium, but did not get
credit in the stats for completing a collection. I've also completed all the Food puzzles on Easy, gotten the Hungry for Puzzles achievement, but did not get credit for completing that collection, either.

Until I have a chance to fully verify that Landscapes and Wild Animals can be completed and that Cityscapes and Food cannot, I'm going to hold off spending my gold on the other collections, or will buy the cheapest one to start off with.

As part of my troubleshooting, I've played everything on Easy two or more times, so I've got some extra gold to burn if I have to delete and rebuy a collection.

Although there isn't a delete function through the normal user interface, I've looked at the user directory folder structure, and there are folders and files for downloaded collections. At some point I'll probably attempt to manually delete and then redownload
a collection to see if that fixes the issue I'm having.

I've noticed the same thing.

Also I would like to know how to delete a collection once completed.

Exact same issue. You can delete the locally stored copy but it stays in your music collection. Although I select delete the music pass song remains. it seems there is no way to remove from phone. and if you don't have windows 8 on any machine you are
completely stuck with no way of managing your collection.
