Does anyone know whether one can actually touch OUT on the platforms at
Stratford without getting an unresolved journey?

I hold a Freedom Pass and also an Oyster card which I used for 'twirly'
journeys.

From last year I was able to travel on buses and underground at any
time, which obviously I can still do.

Now I can travel before 0930 from a NXEA station using PAYG on my Oyster
card but I only need to use it to Stratford, as my Freedom Pass is valid
from thereon.

To be sure, I know I can exit the station with the oyster and re-enter
with the pass but it's a lot easier if I don't have to.

Any advice welcomed.
