Play on the most stable connection you can, so wifi would be better then cellular data in many cases. Make sure your seek restrictions are not too narrow.
I just contacted the support, they advised me to uninstall the app, clear app data from settings and then re install, that solved my problem. Earlier it took about 5 min to search for a game now it searches in about 3-5 seconds. Thank you guys for your input.
