2.   PC
   

3.  During a match. Played lands for 3 turns as normal. once turn was sent to opponent on 3rd or fourth turn. I was unable to play the flash in my hand. Nor was even given glowing highlight on the card. Auto stops giving me a chance to play did happen but i could not interact in any way. only clicking on my glowing  lands turned them from orange to blue and back but did nothing else. had to keep clicking skip turn/pass button on lower right hand side. On my turn I would draw but then would have zero cards selectable in my hand. I could grab them and move them but they did not highlight nor activate. No land would place no creature would enter. I am fairly new so assumed my opponent activated a card effect i missed. hitting pass/next phase skipped my turn entirely, skipping combat phase,M2 etc.. On opponents turn once again i could not play my flash but every stop would happen. I did not even know i had a flash to play so missed it on the first interaction. Opponent attacked and I was able to select blockers but nothing else. My turn again and draw, no land play no highlighted cards. Put a stop on combat phase and was able to pass into it. Did not attack. Passed and went to opponents turn. Same problem flash stops but zero interactions I could do. My turn again and decided to just surrender. to be clear selecting the appropriate mana and then selecting the card did nothing just change the mana borders colors
