Upload 3mf - button next step not active

Good day everyone!
I have a Bambu Studio file (.3mf) — why is the “Next step” button not active when I load the file?

That’s weird. It should look like this:

Your screenshot is missing a bunch more to the page. I’d refresh and start from scratch to see if it shows up correctly. I pulled this screengrab just now so it’s working for me.

Yes, it looks the same at first, but after I attach my file, the “Next step” button is not active.

Very strange. It’s a glitch of some sort. Whether that’s on your end (browser issue) or on Bambu’s end, I don’t know. I haven’t been able to reproduce it myself as it all functions as it should.

What browser/OS are you using? When was the last time you cleared the cache? Do you have third party cookies blocked or a VPN enabled?
