What happened to sort collection by folder?

That option is still on the site.  It looks like this:

If you are not seeing that option, you should scroll the filter options to the right or left to see all the filter options available.  Folders should be listed there.  

Let me know if you do not see it after doing that.

I am currently using an android phone to inventory comics using the picture detection. When in my collection, the drop down box for sorting offers to sort by high/low, demand, date added, etc... but used to show an option for sort by folder. I no longer have this as a selection there. I will check in the morning on my PC and try it that way, but having this available on my smart phone was nice since I am cataloging a few thousand magazines.  After using the quick add feature I can go back and sort by "no folder" and see only the ones I scanned today and then assign them to a folder. 

It should be on mobile too.  You might need to scroll the list of filter options to the right to see it though.  Here is a screenshot showing roughly what it looks like on mobile after scrolling.

Let me know if that works.

Ok. So I have achieved some progress here on the "app" version but the previous functionality is definitely changed. This is what I see normally on the web app when viewing my collection:

The selection does not include sort by folder and the available drop downs do not slide to the left to reveal more options, UNLESS

I turn my phone to landscape mode. If turn the phone sideways now additional options are accessible. This is definitely different than before as I use this function continually.

I'm sorry that scroll to the right isn't working for you.  

Can you let me know what phone and browser you use?  I definitely want to look into this and see what is going on and how to fix it.

Thank you.

Sure. 

I'm using Chrome. 

Quick weekend update:

The dropdown menus now scroll up to reveal more options in the app. So this is a fix for me! Thanks

Great to hear.  I made this change for users just like you.  Scroll doesn't always work across devices, but this new implement works on all devices.

Thank you
