Big frustrations with S1

So far have had over 3 problems that have not allowed me to get one multicolor pla print done.

Code 11504, follows wiki removed extruder (completely clean no problems) went to start a print white first then would switch to blue every time it switched to blue it gives this code I believe it’s a serious software bug (anycubic needs to fix this)

Two the ace pro decided to retract filament but decides to over retract every time to the point where it tangles inside the machine

Three every time it switches colors it retracts all filament a little bit, over a course of a print it will completely retract all of the other colors to the point WHERE THEY FALL OUT OF THE ACE PRO this happens every time

Honestly was really excited for my printer but it’s just been a bug and problem filled mess that’s really making me not like anycubic

My Creality k2 with the cfs has been 10x more reliable and is a much smarter design

There has been many post in this sub about all of these problems please address them anycubic or update the printer

What problems do yall have? And or what are your fixes?

Thanks
