I was curious so I tried to register with a Proton Pass liss which is @passmail.net and they also refuse those. I think they are afraid of services which allow to easily create multiple aliases, because people could create multiple accounts very easily (scammers maybe)? It's a dumb rationale because it's not much harder to create many Gmail accounts but that's the only reason I can think of.

Usually only one axis skips steps, especially since the MK4 has collision detection. A shift in both axes would rather indicate a steel sheet shift imo
Did you losen the idler tension screws? TPE requires that the tension is very very light otherwise it tends to buckle around the gear before entering the nozzle tube. Reducing retractions to a minimum is also always a good idea, as well as limiting the max flow rate.
Maybe you're using light roasted coffee, which usually requires a higher quality grinder to extract properly. You could switch to something darker which for sure will reduce the acidity levels, or get a cheap quality hand grinder. I've had a 1zpresso for a while which does the job, but I finally got a good electric one too because it's only fun for a few weeks to grind by hand for espresso (it takes like 45 seconds)
