If your Nintendo Switch is blocked, there are a few signs you can look for to confirm it. Firstly, if you try to turn on your Switch and it does not respond or displays an error message, this could indicate that it is blocked. Additionally, if you attempt to connect to the internet with your Switch and it fails to connect or only connects intermittently, this could also be a sign of a block. Another way to tell if your Switch is blocked is by trying to access certain features or services. For example, if you try to access the eShop or online multiplayer and are unable to do so, this could indicate that your Switch has been blocked. Similarly, if you try to use any digital content or software on your Switch and it does not work, this could be a sign that it is blocked. If you suspect your Switch is blocked, you can try to troubleshoot the issue by performing a hard reset or checking for software updates. If these steps do not resolve the issue, it is a good idea to contact Nintendo customer support for assistance. They will be able to confirm if your Switch is indeed blocked and provide guidance on how to resolve the issue (if there is any way to do so).
