I love the mobile app and even upgraded to Platinum for unlimited moves :) ( I made some 40 moves today )

There are some small glitches which gives '-36' as error . It would be nice if it provides more meaningful message.

During login: ( I had my password saved . This error showed during my third login)

When I comfirmed one  my move:

Actually, the move was sumbitted. But it was still shown on the listing. When I tried make the move again it pointed out that it's not my turn.

Mobile: N95 8GB model

I am afraid that it is your specifick mobile that returns the -36. In reality is sounds like it is a connection error, so trying again should solve it. In future versions of the app it should say "Connection failed. Try again."

I don't think it's an mobile error message. It pops up from the chess mobile app. I am sure the develpers know what the error message conveys.
