See the issue in the Bungie forms.
A screen will pop up that your Taken King trail has expired. All TK content is now locked. Uninstall/reinstall does not fix. Nor does cold reboot of Xbox One.

I got the same message and I ignored it completely, so far I haven't ran into any issues at all.
Have a nice day or afternoon or night "ABomb" :)
I ignored mine also and I can still play
