Yes, he answered you right. Developers have announced (and it has been repeated here often) that they don't have time to upload ROMs to servers, so they committed to do it once per month - but it seems not even that have been possible until now.
By the way, if you're still with that version, you wouldn't ever receive any OTA anyway, since for that it is needed to have TWRP installed (which could have been done receiving the last OTA when the transition was made, or anytime later by following the first post's directions).
