Hi @Juan_Gabriel_Fernand and welcome to the Forum! 
a
Thank you for taking time to report this! You are correct here. The ability to sort tasks in a tag’s view is not available. Unfortunately, this is not a bug, but rather a product limitation.
There are a few existing threads requesting for this functionality in the #productfeedback category. I would encourage you to upvote it if you haven’t yet.
Since this is not a Bug, I’m moving this thread to the #tipsandtricks category. Please, let me know if you have any follow-up question!
Have a great Thursday!
