No major issues. Some things have changed to make it more user friendly, like double-tap upvotes, but the use is very intuitive and I havent had any major problems like sudden crashes or freezing. There is still the occasional server overload, but even then, you are still able to view content, just not comments (UPDATE- thus is happening more and more frequently). You can favorite gifs and memes in the comments, too. Downloading for use in a private conversation is easy, and theyve also introduced a chat feature. I would very much like to have the ability to organize my favorites (its truly a pain in the butt trying to find the right "reaction" meme quickly, or to easily find that one "dank meme" that only your friend would appreciate on your level).
