Have I chosen unwisely?
I have (or had) the first row in ET to AMS tomorrow (was row 8).
I have gone into check the seat choice and now while the seat numbers are still as previously selected, there is no seat map of the cabin. It is also listing A, C, D as middle seats? On the app and BA web site.

If I make a dummy booking ET now starts at row 9 (and only one Y fare left I think).

If they have moved the curtain back, then I guess they will re-seat us further back, however not sure what else was left. In the non BAEC dummy booking only seats left are right at the back of the plane but i guess this is due to theoretical seating.

Is this going to error at ONCI or should there not be some sort of notification before hand?
I cannot select anything elsewhere in ET due to the error in app and on the site, so if nothing else, I will call up and ask them to have a look.
