Well, my quiz again has another error that I don't know how to solve. This time it works the first time normally, without any errors, it goes to the score screen and then to the home screen. When I start the game again, to answer the questions, this error appears, and the timer decays a little faster. It's not a big problem, but it's still a bug. Does anyone know how to solve?
Hello Caio
I see that cronometragem's viability is changed in various parts of the code - that might have something to do with the problem. It is usually not a good idea to make components disappear, only to reappear later. Imagine if your car dashboard did that
