I also just tried that and I did not get my weekend minutes or my mobile to mobile... Only my regular mins. I enjoyed seeing how much of it I was not paying for. =(

Just an error they are working on or is it indeed like that from now on?

The only definitive information I can locate has to do with a change to how it displays for family plans, but the coincidence of the dates (1/23) and the new display is too great to discount. It looks like we're just reporting whenever minutes, and bonus or overage minutes if applicable, which makes sense. Usage for all buckets are still viewable on MyTMobile, but I'd say #646# will only be displaying whenever minutes from now on. Subject to change without notice, of course! 🤣 😉
