What is the Apple Arcade app?
Chess.com's mobile app for Apple Arcade. I have both the regular app and the one exclusively available for Apple Arcade which is subscription based. All the bots are unlocked but otherwise it doesn't offer much.

It wasn't a classic game, although I do think your effort to establish a London System set up was worthwhile. The cheaters are mainly around the 2000 level. I think your opponent just beat you by playing better moves in the midgame. It happens to me all the time.
That's kinda what I was thinking. It just blows my mind how well I can be doing and then one mistake loses the whole game.
Here is a game I played on the Chess.com Apple Arcade app. My opponent's username is hidden and I cannot chat with my opponent, report game, or share game as a PGN or FEN. There is no timestamp available either so I have to manually add them. This is a rapid game with 15 minutes and 10 additional seconds upon a move for each player.
Anyways, this game frustrated me because my opponent had several minutes less than me but found the right move after I made one mistake. I can't tell if he/she cheated at the end and I can't view any past games nor can I report him/her so I so just have to trust no foul play occurred.
