You could have a bad 12 speed cassette. I would try another 12 speed cassette if possible, do a hard reset on the groupset and see if that will help. If it shifts an 11 speed cassette fine, it should work fine for 12 speed.  Something tells me the issue must be hardware related. So you'll have to do your best to narrow down the possibilities.

Thanks everyone for the suggestions, it is working!!  A combination of doing the factory reset via the app and performing the calibration again was the trick.  Speaking of hinky cassettes, I think both of my Ultegra cassettes are weird in different places.  I get some chattering in a couple of places on one and the other has a bad tooth on the 16 cog that needs some shaving, but other than that, I can shift equally well on ER9 and Ultegra.

I'm running a 12 speed cassette with no issues. Check your lower limit screw and also try fine tuning in the app. I have my ER9 tuned using gear protection and optimal shifting for climbing in my small chainring. Though I can shift big/big and small/small no issue.

Also check that your derailleur hanger is aligned properly and that your cassette is seated properly in the freehub. I've noticed 12 speed is a bit more finicky so any little thing out of adjustment can affect shifting.

Worst case scenario is reset all settings using the app and start fresh. Make sure to double check if your RD is properly screwed into the derailleur hanger. Good luck!

It's not a limit issue that I can tell but I will double check. When I back out the screw it will over shift outboard. I can adjust the trim on the 12 cog to go over to the 11 and it will stay there, but it will not shift to the 11 and stay,  I do not have gear protection turned on and it is doing the same in both chainrings up front.  Next stop is the factory reset and redoing the 6th gear calibration.  Or swap back to the 11 speed cassette.  Yes, I use 12 speed chains on all my bikes.

Issues with 12 speed cassettes.  I am having a problem getting it to shift into the last 11 tooth cog on two different wheelsets.  I have backed off the limit screw so much that it has over-shifted on the outboard side so I don't think the limit screw is the problem.  It will actually shift to the 11 and then about 2 seconds later it shifts back up to the 12.  if i hold the button down, it will stay in the 11 but as soon as I release the shift button, it shifts back to the 12.  I did replace the wonky looking narrow/wide type pulley with one from a 6800 ultegra derailleur I had laying around.  That helped shifting all over but the 11 cog is a mystery.  When I use an 11 speed wheel and change it to 11 speed in the settings, it has no issue shifting the entire range.

i used to use a battery pack thinking it was charging, it wasn't really. I've been using a wall socket, works much better. I wouldn't charge less than once a week though, the battery doesn't last that long (I did use $hit batteries, to be fair, i tested their capacity at 320-380mah each).
Thanks for this.  I ended up getting these:  EBL14500 3.7V 800mAh Li-Ion Rechargeable Batteries from walmart.com. So far so good!

Does the shimano funnel fit the hood bleed port?  If not, what is the best bleed kit made for this er9/x groups?
