I've had quite a few schedule changes pop up the past 2 weeks, including on a couple upcoming trips with the family (wife and 1 year old, so infant in arms). For each change, it split us into window/aisle instead of sitting by each other (which would make sense if we had been in a pair on a 2-3 and not moved to a 3-3 aircraft). The issue is for each of them when I try to change the seats so we're sitting together, the seat maps are either 'view only' (including for changes made over a week ago still) or I get an error message that we have a special reservation and can't sit in an exit row (which, I'm not trying to sit in an exit row, I'm just trying to move my wife and daughter next to me in the same C+ row we are already in). Then I'm forced to call in since I yet again can't make changes online.

Anyone else having constant issues with seat maps, schedule changes, or modifying flights online?
