Client Bug and Key not dropping?

Hi. everytime i start the client i receive notifications that my friends opened the gifts i send. this might be a bug? on other subject it seems im not dropping keys. i play with premades and im having a lot of s+, s and s- and its dropping keys and chests to my premades (even when they have A and B scores and nothing for me. i dont mind that but since the new season start didnt drop a single key fragment to me. thanks
