Error "Uh-oh, it looks like we have our wires crossed. Intenta nuevamente más tarde".

For some unknown reason (well, at least it’s unknown to me), I find that I no longer have to disable Brave’s 'Block fingerprinting' setting in order to reach T-Mobile's login page. I think I first noticed this the time before the last time I needed to login. I just thought that T-Mobile must have finally gotten to the root of the problem and found a solution which fixed it ..

I did a search online to inquire as to what blocking fingerprinting in Brave is equivalent to in Chrome ..

Brave's fingerprinting protection is a privacy feature that makes it harder for websites to track users by collecting device and browser data. Brave's "farbling" features add a small amount of randomization to browser features to confuse trackers. 

Other ways to protect against fingerprinting include: 

• Canvas Blocker: Prevents malicious scripts from using the HTML canvas element for fingerprinting. 
• Tracker blocker: Cross-references lists of tracking scripts and blocks attempts to load ads. 
• Disabling JavaScript: Most trackers run on JavaScript. 
• Changing browser settings: Major browsers have settings that disable certain types of tracking.

So seemingly this issue MAY have something to do with T-Mobile tracking users via data collection(?) And I'm not saying that I know that it does -- because I don't know; but perhaps this comment may provide some insight as to how to think about the issue if you're still unable to access the T-Mobile login page ..
