Arena Blitz and Rapid

I am very happy  that the Arena format has been introduced to Chess.com; it is a very welcome addition; I actually am wondering why there is no 10 min format for the Arena. Are there any plans to introduce it?

Also I noticed that it is impossible to access the Arena tournaments from the Chess.com mobile App (android) - except if I am doing something wrong there

Yeah, Arena events don't show up on the app. 

As to 10 minute events, based on how scoring works, with more games giving more points, I don't think the format makes much sense at that time control or longer ones. Bullet and fast blitz do.

Personally I don't see a reason why 10 min games cannot be the same as blitz and bullet; I don't see a difference except the fact longer playing times; anyhow since we have the strike point system and top players will play between to determine the winner it is pretty much the same except the time differential as I mentioned 

The thing is the Arena format awards players that complete more games; well, win or draw but the more games you get in the better your chances.

Well, if there is a chance to vote, I would vote for rapid arena with longer time control format.
