2 chatgpt apps?

So Today, chatgpt has been bugging out for me today, no big deal, went to go see if there was an update, but it said it wasn't installed, l thought it was a glitch, whatever. Downloaded it, and its a completely different app, but still has all my saved chats, the black app is what l normally use, and the white one is the new one. Can't find the original app on the playstore anymore, anyone else run into this weird issue?
