On the Android app, could we have the ability to flag comments we've previously upvoted? This is a fairly regular need for me, and I ran into it again earlier: I flag comments as obsolete when they are, and fairly often, one of them will be a comment I've upvoted.
For an example of a typical case: a comment suggests a great improvement to a question, I upvote it, the author performs that improvement, the comment is now obsolete and (on my PC) I flag it as obsolete. The comments get cleaned up and the question moves on.
There's a request that's been around since 2011 for the site itself: Allow flagging a comment after upvoting it. It's implemented by SOUP (as described here), but the Android app doesn't have a SOUP available to add this functionality to the app for me.
