Why am I not getting exchange credits on TCG Live?

It's been about two weeks or so where I have not been getting credited for exchange credits while completing daily tasks on TCG Live. I rarely exchange for new cards and my trainer points is thousands of credits higher. I am also having issues where I need to select cards either pokemon, trainers, energy, prizes, etc and it isn't working. It's irritating and at times upsetting that I have lost and or conceded matches because I select the card I want and it doesn't want to drag, slide, and sometimes even highlight or expand when tapped. Another noteable issue is that when I use Rocket Watchtower Stadium card, it does not work making the card useless. I have played matches with others and it works for them. I add the card to my deck, and yet again, it doesn't function.
