I was playing a casual tournament of three check chess (I was conducting it) and suddenly during one of the games all the pieces went invisible. I may have accidentally pressed something on the keyboard but I am not sure.
When I play on my mobile or when I play anonymously on lichess (through incognito mode), I am not facing this issue.
This video of someone else from the past sums up my problems:

The person who uploaded this above video also faced the same issue. He had posted a query here. The solution given him was to disable the blindfold mode from preferences. When I open preferences on my account, I do not find the setting for blindfold mode. How do I resolve this issue?
