I have the same issue. It occured in Bambu Studio and Bambu Handy App. They have just released an update to the Handy App which has restored the functionality but Bambu Studio still has the error. I am guessing that v2 of Studio has intruduced a regression or bug that needs to be fixed.
I can access it from my local WiFi network, but as soon as I’m off local network then I can’t access or start prints remotely. This is affecting my business, I rely on being able to start remote prints.
From what i am reading about others past issues with updates: Once I find an update that works well, never update it again lol.
I just got my first P1S, I have yet to get the printer to even recognize any wifi connections at all. Seems to be totally blind. Which I am ok with, I will just load my files with the SD card, but really wish they would have put a USB port on any of their hardware. Micro SD is just annoying to use and feels like its really behind in tech.
I get an error that my 128 gig card has an error. Tried reformatting a couple of times but still get the error on Bambu Studio. Printer shows card is installed and 119 gig available. I can send a print to the printer and prints just fine. Bambu Handy does not show I have an error with the card. I ordered a 32 gig card and formatted it and both Bambu Studio and Bambu handy work just fine accessing the card.
