For a few weeks now, the checkin process has been crashing if I try to view/change my seat within the checkin period (within 24hrs of flight). I can view and select seats fine, so long as the checkin period hasnt started.

The error I get is:
"Unfortunately our systems are not responding, so we are unable to process your request at the moment.

We apologise for this inconvenience and suggest you try again later."


Anyone else have this problem?

[Yes, I know I should choose my seats in advance but I'm lazy, and/or often do last minute bookings/changes]
