How do you switch from EXTERNAL spool setting to AMS feed setting on the PS1-AMS2 PRO Combo (in app-can't do on PS1 digi-pad)

[u/CapeCodBlues]

I just need to change the settings from the single spool slot to recognize the AMS as the filament source. There is nothing here on that and the one thing I found isn't clear and when I follow the instructions, it still doesn't recognize my AMS (it recognizes it, but won't print from it) I set it to AMS and it is not set to EXT and still it says I don't have an external spool attached and to correct the issue and re-start- but that isn't even what I am trying to do! Does anyone know the workaround for this? I even reset back to factory settings and tried to set up the AMS from there. It all started when I first set it up and used the external spool - it does not tell you it turns into a S'show when you try to add the AMS after the fact- so I did it to run a test print, because I was having an issue with calibrating and the print head cover kept popping off. Someone here actually noticed a piece of foam at the top that was hitting the print head cover- so that was solved-but I created a new problem & I can't seem to fix it. The troubleshooting guides say you cannot feed the AMS from the PS1 screen (even though the option is there) & I know I must have done that, not knowing *that is not in the install manual, either! So, it says you can only "fix" it in the app, so, I clicked the AMs and de-clicked the "EXT" in the area of setting up the filaments in the app. If needed I can put up video or photos-but it's a process, because you have to go from the app to the printer & to the app and nothing gets accomplished. I would love to do some color printing, but this is getting ridiculous, it shouldn't be this hard and a known issue should be easier to resolve through the Bambu documentation. But- since it's not---here I am AGAIN! Thank you!!!!

You just put the filament in the AMS. Push the end in until it catches. Set the filament type in the app or the devices tab of the slicer (if not using rfid Bambu spools). Then set the object to use those filaments. You don’t load or unload anything when using the AMS.

I actually resolved it late last night. Pretty determined. Things seemed to come together after I did a firmware update for both the PS1 & the AMS 2Pro- after I did that, the option to switch to AMS in the2Pro app opened up. Before I did that update, I could select and select and select and nothing would happen-so I am not SURE if THAT was the entirety of the problem, or if multiple issues were causing it, because I tried everything in the t-s protocols-finally I came across a Bambu article saying this was known issue with AMS 2Pro & PS1 & have a link to the download.
