You’re right, it isn’t. But if you read this long a$$ thread the consensus is it’s a mounting problem involving the plastic, not the metal.
It’s generally believed that it happened after the machines were shipped. They probably tested the machines’ beds when cold then did a quick warmup test to check the heater, never rechecking the bed.
Before you say how that’s dumb, remember we’re discussing a production line here they certainly didn’t run the machines for hours at temp, that would result in 20 machines a week or something… LOL.
They’re handling it. Be patient it takes time they have to:
- Study the exact problem
- Have a discussion of possible fixes
- Get the fix designed
- Prototype to ensure it works
- Discover the new design has some other issue like wiring wrong or rubs
- Modify the design
- Create new prototypes
- Stress tested like hell and examine the results, possible design change.
- Get new molds made. Note this is almost certainly at a sub manufacturer so they’re dependent on their schedule.
- Have test runs of the new design molded
- Find there’s some issue with the mold, wait for new molds to be made
- Wait for manufacturer to run off a new batch of bed parts, again on their schedule.
- Have parts assembled, most likely by yet another manufacturer so there’s shipping involved and yet another manufacturer’s schedule to consider.
- Discover the there’s a delay on the plates or heaters or wires or connectors or … {Sigh}{Bambu team begins to beat heads on desk}{Again}
- Finally gets beds made, shipping time back to assembly line.
And there’s all sorts of other possible roadblocks.
This is not to you @Thrawn, I know you are a voice of reason, but I JUST DON’T GET WHY YOU PEOPLE DON’T GET WHY IT TAKES TIME! THEY DON’T JUST WAVE THEIR HANDS TO GET NEW BEDS!! {End Rant Mode} 
Seriously, it takes time. They’re hard at it. Ranting here doesn’t help, it only works to gets it off your chest, eh?
I’m as frustrated as all of you, my bed had a .93mm bow! I Alum tape fixed for now, I want a new bed too, but it’s just not a quick thing. Months not weeks. 
Thanks for letting me get off my frustration @Thrawn 
Cheers!
