Be able to change photo categories after posting them.
You can! Tap/click into the Photo Detail view of the photo of the image that you’d like to change, tap the edit button, and from there you’ll be able to shift the Categories selected.
This has stopped working for me. I can edit the description, but I can’t edit the categories…they are all greyed out. (Also, the window only shows a few categories, the rest are clipped)
You can only select up to three Categories per image. If they’re all greyed out, you’ll need to deselect one your previous Categories to be able to select another.
