I’m having the same problem on the iPhone app. When it gets to step 4 ‘updating collection’ I think.  It errors ‘error uploading collection please try again’.  I’ve tried 100 times over the last 4 days.

Then you are out of luck until they fix this. Of course, that might never occur. If you have a small collection, you might want to consider using a different app. If you have a large collection you should consider purchasing the PC app. It will extend the life of your iPad app and, more importantly, it will allow you to move your collection to a different iOS app. If you have an Intel Mac, you can use Bootcamp to run Windows 10 for free.

Don't expect any iOS updates but since this recent upload issue is a new server problem, there is a chance it will be corrected.

Collectorz also claims to be able to import DVD Profiler export files, but you need to subscribe to their Movie Collector web service or windows app as well as their iOS app.

I am still having error uploading my collection.

I signed in to my online account today.I noticed that it showed I have 40 titles, last upload March whatever 24, I have over 1200 titles in my collection. So it says to reset my collection to delete it, so I did that and then selected my settings, so I tried again and it still won’t upload, get same error with the iOS app.

I would try deleting the iOS app and reinstalling it, as that sometimes solves issues, however, doing that would delete my collection from the iOS app, and I’d have to start over, plus this is most likely a server issue as that is what changed.

Also, I recently purchased the 4K aliens, and in trying to add to my collection it doesn’t come up, so I tried to search by title with blu-ray and 4K on, and no results, so maybe there is more than one server issue here.

I am hoping the ppl who run this site are reading this thread and trying to solve the issues but not sure if they are, it’s been over a month with no communication.

Quoting RMC:

I use the iPad and whenever I update I get that message, but it still mostly updates.  Sometimes I have to keep entering the new discs with barcode several times (I don't hve the desktop version to submit titles) but eventually they take and the entries stay.

Um, yeah, I don’t get this, for me it doesn’t update at all.

It’s frustrating because I have over 1200 titles on one device and I can’t update it, can’t get it on my other devices. I don’t know what to do, I’m assuming not everyone has this issue, I thought about deleting and staring over with a new profile, but, I don’t know if that will work, plus that would be a lot of work and time I do not have.

Ok it's clear we are not gonna get a fix so time to find alternatives.
