Uploading content is frequently frustrating. It just doesn't let you, sometimes. No explanation as to why, and the FAQs don't help much. Can't see all of the people I have chosen to follow, regularly showing only a narrow selection, and shows me stuff that's old and/or out of date. Editing and filters on my film uploads never work, either. Seemingly arbritrary reasons as to why I can't boost posts - shouldn't I be able to boost supposedly substandard images if I want to? That's my choice.
