SyncUP Kids changed to T-Life and now all I get with the new app is an error

I would recommend remove the line and explore other options for our kids watch, Tmobile staff didnt have any reponse, including the one at store have no ideas about this product as much, now I cannot check where is my kids at all, i would just move on insteading of waiting for tmobile to reponse, maybe 1 year later

Fix this nonsense or I'm canceling my service. Hey Tmobile, fire your software team because they suck! Why do you feel the need to innovate for the sake of innovation and break your products for your customers? All you've done is piss us all off. I want a refund for my service because your "innovation" has made it unusable. 

This happen to me. I can't connect to my kid watch as a guardian. I called and spent an hour talked to tmobile customer service, they told me to do uninstall and reinstall T-life app, reset the network, or even login to tmobile website to track my kid ( which is fkin dump cause there s no option to track kid from the website), and what I got is "sorry, we can't help you". All day frustrated

Good evening everyone. SO...the way I fixed this issues was

1-Uninstall the Sync Up Kids aplic. 

2-Uninstall the T-Life aplic.

3-Go into my T-Mobile app and log in and make sure that is all up to date and stuff. (I never set up my T-Mobile app, so I decided to make sure that wasn’t causing and issue)

4-Reinstall the App T-Life directly from the Play Store and log in.

5- It should be working.

NOTA: 

So since the T-Life and T-Mobile apps looked EXACTLY the same, I decided to uninstall the T-Life aplic. And guess what...The functions of Sync-Up Kids were still there in the T-Mobile app. I even logged out, turned off my phone and powered it on again just to make sure that it wasn't some kind of error. Yeah...the T-Mobile app and the T-Life app are essentially the exact same thing. So there is no need to keep the T-Life app. However, I did only notice that the features of the Sync-Up Kids app were there after I installed the T-Life App and logged in. (maybe I didn't pay attention to this fact and could have saved a step). I have since deleted both T-Life and Sync-Up Kids and it's working just fine...well...fine for what it is. The GPS tracking is SLLOOOOWWWW. I really hope this helps someone.

I called in and was told the app is fine and "improved". If I can get into the app to use it i have to clear the data daily and the tracking, if I get it to load, doesn't work well. 

Really need to bring back the old SyncUP KIDS app but seems TMO doesn't listen to their customers. I've been looking at alternatives to the SyncUP watch due to it now working 

Same issue, tmobile had the nerve to tell me I need to create a new email address which is not the solution it is and app issue
