If your pattern of behavior is to push the load to another team consistently when there is a problem with a specific area, then we will have to start assuming that you either have no ability to deal with the problem, no knowledge of the area with a problem, or both. This forces the rest of us to conclude that we are wasting everyone’s time including you on the problem-solving meetings and emails.
Once this is the case, you will be left out of the loop. Once this happens, why do you start complaining about not being included on our discussions?
