I just got the app for iPhone, have been using the PC version for years. I added a bunch of movies and uploaded them. For some reason, all of the new additions are at the top of the list in no particular order. All of the pre-existing movies are still alphabetized. Any thoughts as to why this might be?

Not convinced that's the issue, clicking Title in the collection listing should sort them alphabetically regardless of the setting ticked under your link. In this case I've tried this with MrCreel's collection and the latest additions still don't sort alphabetically.

MrCreel how did you add the latest titles to your local collection and online?

Also you may want to check the sort titles in your PC version for those titles, just in case there's something off with those.

Did you try Lewis' suggestion just in case it works? You can still access the site from a portable device, it's just not as easy to use.

Setting that aside I'm taking a guess that you originally uploaded your online collection with the desktop version and updated it with the iPhone one for the latest additions?

Which suggests to me for some reason that updating it from one then the other doesn't play well, but I've never done this so don't know for sure.

I think the solution would be to re-upload the collection from the desktop version if you can.
