TS Header Is Invalid or Expired.

[kel70]

How many of you are getting this message when you try signing into your Sephora account on your phones? I can access Sephora Canada on my PC, but when i try to use the app on my phone it will not sign me in, instead it says this.... TS Header is either Invalid or Expired. I tried changing my password, re-installing the app, clearing my cache and cookies and i scanned my device for malware. 
I don't even know what this means, let alone how to fix it. PLEASE Sephora, help a girl out here!?!?!

Hi, I'm having the same problem. I was logged in today, in the middle of adding to my cart. When I refreshed, I was somehow logged out, with "TS Header is either expired or invalid" and now I cannot sign back in. Clearing cache didn't help. How do we fix this? Thanks!

@kel70 I have received your PM and will reply shortly.

I’ve had this issue for two days and if you delete and reinstall the app it worked for me.

I just tried that for the 4th time and it didn't work. 😪
