This is seriously affecting my productivity.
I'm paying for the Pro plan which includes access to 5.3, my config is set to 5.3, the UI shows 5.3, but I'm getting 5.2.
I've already lost time working under the wrong model without knowing it.
If I'm not notified, I have no agency over my own workflow.
I'm making decisions, reviewing code, and building on output that I believe comes from 5.3, when it's actually 5.2.
By the time I discover the switch, I've already committed time and work I can't get back.
If you need to reroute me, at minimum tell me so I can decide whether to continue, pause, and escalate to support.
