From my point of view, you expect problems with these sort of IT integrations. Only a fool would expect 100% on day one. Any sensible person would give them 2 weeks to get their house in order.

Overnight, for eg, they have correctly adjusted the status of those who did a Plat challenge from P to PP.

Personally I think you just look stupid knocking out blog posts moaning about glitches in an IT merger impacting 110 million people, especially as no-one is losing financially.
