I've become incredibly frustrated with the upgrade splitting because it almost always leads me to getting split from my companion in E+.

Several times, I've been traveling with my GF who is a silver. When I split at check-in, she always seems to get separated from me when we already have seats in E+ together. Last week, we had an aircraft substitution (737-800 to 737-800 different config) and I noticed we both ended up separated in E+ in middles (was supposed to be window and middle). I called the 1K desk and there was nothing they could do and told me not to split the reservation then. If you can move my companion away, then why can't you move the person in her seat? GF still inherits my 1K status, so what gives?

How hard is it to ensure that my companion and I are still seated together? She's a silver, so she should be eligible for E+ at check-in anyway. Should I never split so that I don't need to babysit our reservations / seat assignments?

This keeps happening and we're both frustrated.
