Accent mark
When I try to put an accent mark long-pressing a letter in my keyboard, it suddenly block itself not alowing me to continue typing in the application I'm using. For example if I want to put an à I just press the letter a for like a couple of seconds but instead my keyboard block and do not let me type any other letter or number. I'm using Big Sur 11.2 on a MacBook Air.
