Love the game, app needs work

Since the most recent update with gym battles and raids, I have been drawn into playing even more. However, I am getting frustrated with the bugs. After I take over a gym with friends, only 1 of us is able to leave a Pokémon in the gym. From the looks of it, a lot of people are having this problem. Another problem I recently started having is my avatar doesnt travel with me but stays in one spot. As you can imagine, this is extremely frustrating as I cant hatch eggs or get candy for my buddy. Please fix!!
