Just a heads up. Did my yearly retirement visa today and it went smooth save for the fact there is no TBB bank downstairs at Immigration Changwattana anymore. They said moved to building A but that is not the case. It is on the road between Buildings A and B and you have to go through a military gate to get to it. Advise to update somewhere else as its not easy.

I had a 9:30 appointment but missed it due to having to run around to the bank for passbook update, arrived at document checking at 10:00, documents were in order and had my passport back just before 11:00 which was reentry permit time, that took less than 20 minutes so not a bad day at Immigration. 

A few years ago this also happened to the SCB bank office downstairs in the B Building. It was suddenly closed and people were advised to go the office in the Big C Chaeng Wattana building. This only opens at 10.30 am. Of course you could go to another office but some have no clue about the bank letter (even if shown an example).

Anyway an hour between document check and return of passport with signed extension seems typical (at least in my experience) for on-line appointments.

OP, thanks for the update.

Personally if dealing with CW for annual extensions I would change banks to one that has branch in Building B

I have had the account 34 years so no wont change it. My normal branch can do it easily now so just make my appointment for 10:30 am and all is good. Finally have the documents down so its easy. They were impressed to have had the same account for so long.
