GroupMe App not showing a group IIm added to?

So I have a GroupMe app which I use frequently to communicate with my soccer team, well my tennis team decided to make one and another team member added all of us to it except the problem is, I never got an invite to it or anything and it shows that IIm in the group via her end. Although for me, the only group I'm in is the soccer one. How do I go about getting into this group? Why didn't it send me anything about being in it? I have an iPhone also. Anyone else have this problem and how did you fix it?

Well, what you did may not have been a foul. What were you protecting? You are allowed to, protect your face and chest. If you just reached up, and grabbed the ball. A whole different issue.

In any event. Get over it. In a game a yellow card if intentional. A red if you stop, a goal, scoring opportunity.

It is all part of the game!
