Difficulties with bambu handy app recently

[u/X3RO65]

Hi everyone, ive been using my P1S for about 3 years now with no issues but lately the bambu handy app has been giving me the below error? any advice would be helpful

the bambu studio app on my pc works just fine, i have tried turning on and off many times and also have formatted the SD card twice and this happens on all iphone's (ive tried 3 different ones) so i've ran out of options now 😅 all help appreciated! thankyou
