Yes, I think almost all of us see the LOU3 amount doubled instead of seeing a separate LOU4 credit.
Some reported receiving SMS about unenrolled promotion but it doesn't seems like it's widespread.
Someone on Reddit [reddit.com] explained it and said there was no need to worry. I don't quite get what he meant but seems like it's just some system error from T-Mobile.
Wrong! They said that if you take advantage of the November free line that you are not going to get this promotion in December for free! They were haggling me to give up the free line I received but I persisted. They better not charge me anymore than I already pay. Otherwise this may become a class action lawsuit possibly!!! I'm so mad now!!!

I would do this trick from 2 pages back:

Google chrome -> my t-mobile account page -> development tool -> manageaccount -> Network -> XHR -> Response -> lines -> 0: Object -> aal -> discounts -> 0: Object (namee: "2020 Line on us 3", code: "20Q43S", ....)

This will find which line has the "2020 Line on Us 3" active on. and which line doesn't have "2020 Line on Us 3" promo.
Also you can find the start-date of the "2020 Line on Us 3" promo so you can debug more on where the problem is.

Heads up, you've been un-enrolled from T-Mobile your promotional service discount as the account no longer meets promotion eligibility criteria. This isnthe message I received from T-Mobile this morning. This is terrible on the part of T-Mobile because they never stated that you can't take advantage of both deals for free lines. People on this thread have been saying they have received 7-10 free lines during their time with T-Mobile. I'm so angry!!!

Yeah I still can't believe that people were able to get 7-10 free lines. Did you try reaching out to TMO t-force to see if they can fix it?

No, my understanding is kickback was removed on all magenta plans. And if you didnt have it before you moved to magenta you cant get it added anyways.
Even if you had it before and moved to Magenta, KB will be dropped by the system as it's not compatible. When you hear those who get KB you know they re on T-Mobile One plan.

I spoke to them on the phone and they said they will get everything straightened out and my plan will remain the same without any additional charges. We will see once I get my bill. If they screw it up I will be very angry and somebody from T-Mobile will get chewed out!!!

I wonder how many T-Mobile customers got this same message or are going to receive this same message during the upcoming days. Terrible optics and service by T-Mobile!

That's correct. I had it. Moved to magenta without knowing and got dropped. Today I moved back to One and it was reinstated.

Rep confirmed its glich. Basically its removed LOU3 and then added back. So it will take time to update system

I just added a line through App text message. I do see SIM card charge on my card. I do not see any change in my account and don't see new line number also. How long will it take for the new number/line to show up in the account?

Stop by at Costco today, got a free SIM card and activation for free. Indeed, the guy even gave me the form for $100 BYOD rebate (12/20 to 12/28) as Xmas gift. So worth a try....

I think I have more lines than you, we might have Magenta plus but I do have the 12 line plan, which is different than the regular magenta plus plan, how many lines do you have?
taleefoonkaDude, I only have 5 free lines, Some members reported having 7-10 lines free
​Yup that might be possible. I only have 6 lines (now after adding this free line). I originally had 4 lines with 3rd line on us free promo. And then now I have added 2 free lines.
