This is the Smarty Community Forum, we are customers just like you.
For us to be able to help you, we would need more information than solely “age restriction”
HOWEVER, if you wish to remove the age restriction on your account so that you can watch adult content, this question appears on this forum 2 or 3 times a week, so search and you should find the answer you are looking for, assuming that you do indeed want to remove the age restriction, so that you can watch adult content on your device.
