Can I view past games on the mobile app (Android)?

Oh, huh. I can't believe I missed that. Thank you!
For future reference, here's how it works:
When you open the app, you should see a tab called "Completed games" (scroll down if needed). Tap on the header, and there you go.

I can’t load up all my games, I’m in the games archive and I can only view about 50 of the 7000 I’ve played.

There should be an Archive button at the bottom or your recent games.

Hey how can I use my database past 5 moves I really don't know
You have to use Game Explorer and change the database to the option My Games

Edit: Solved.
On a computer, I can go to my, for example, Blitz stats and click "Games", but I can't do that in my mobile app (I can't tap Games to see my history).
The only way I can find is by navigating to my profile on the app (which also doesn't seem intuitive; I have to find an old chat log and click my own profile to get there). Then I scroll down and see my Completed games, but it only shows a few of the most recent ones.
