P1S speed control from both Bambu Studio and mobile app not working

I tried to remote change the printing speed from 100% to 50%. I tried both Bambu Studio and my IOS app, but it did not work, and the speed is still 100%. The only thing that made it work was manually changing the printer control panel. Has anyone had the same issue?

Is it possible you were trying to change it when it was doing the start up procedure like bed leveling and if so that is probably y it usually does not let you change the speed if it’s do that stuff in the beginning but if not I would recommend you update your printer and bambu handy and bambu studio and if that does not work I have one more question does the live video if not it could be your router is on the wrong wifi security type
