9) I am frequently getting a "No Active Internet Connection" when playing Online Chess. I've seen this since the first version, but I've seen it in enough locations now that I am pretty sure the problem is with the app, and not with the actual connection. I've seen it on both WiFi and strong 3G connections.
The behavior is this: I bring up a game where it is my move. I wait maybe 5-10 minutes. (I like to think deeply.) Then I finally select my move & confirm it. Now I get the error. My move has actually been transmitted to the server; I just can't pull down the refresh to the client, and no subsequent games will show anything either until I restart the app. After restart all is fine.
Yeah, now that you mention it, I was getting the same sort of behaviour last night when tinkering with new account set-up. I'd get the "no connection" error in the same context each time (submission of new account info), but in all cases, my account was actually created.
I had this problem today in a well 3g covered location.
I'll snap one this evening if it happens to me again.
11) Playing vs. Computer in a 5 min game -- taking back a move resets both players' clocks.
12) Playing vs. Computer in a 5 min game -- after taking back that move and re-doing it with the right double-arrow, the computer made no move. Clock eventually expired with no action.
In general, I would assess the status of the app as follows:
I would think seriously about making some focused improvements here before you release the app. While chess.com users will probably be pretty tolerant of the minor warts in the other sections, that's not really your audience -- this is for the world at-large who are looking for good chess apps on the iPhone. A bad star rating is difficult to overcome with subsequent releases.
