Hello cookantwan, I would like to break these issues up into two parts.
1. About the match connecting issue, that is strange. Can you please take a screenshot of your issue and post it here? So that I may be able to diagnose this issue correctly and get you the answer you need.
2. About the M being censored, it is a bug and was not intended to be this way. Aeria knows of this issue and I'm pretty sure they're working on getting a fix implemented soon.
