I’ve had a similar experience, but only now can I relate such to others and a possible problem. Curious.
I’ll have to pay more attention and try other varieties.
Thus far, I’ve only noticed inconsistent results from frozen hashbrowns and whole Russets used for a variety of purposes, including air fries.
Interesting, that we’re all having similar experiences.
We’ll have to come back to this thread and report back with our experimentation results.
