My regret about your issue. I'm not qualified to assist you in this problem. My job is to monitor the activity pages of members. That is enough to keep me busy. Perhaps you may contact the techies by hitting the HELP button in the bottom left hand corner.
If you need further assistance if that doesn't work, please email me back.
Regards
Bizarre- When I connect with Chess.com via my Chrome browser, my opponent's bishops are invisible.
