Nothing load-nothing?

I love this app, and everything. BEFORE I had to go in group chats and wait for ALL msgs to load before I could exit out (I get 3,000 everyday) IT NEVER FINISHES. ?? NOW since the update I cant even load one msg. And it keeps showing Im getting more msgs everyday. I know this isnt easy but I liked Line before the last two updates, it was working perfectly fine.??
