Your experience is the same as the first JQ flight to Bali last month. That flight arrived about 1 hour 45 minutes late, due to difficulties boarding passengers.
JQ screens at check in have out of date rules for Bali, which have caused delays, as passengers grab their mobile phones and try to comply with these out of date rules.
BTW my SIL was on the same flight as you. It was his first flight on the Bintang Express!
My wife flew to Bali last December. She is not tech savvy either and took hard copies of all the required documents. She found it a lengthy process, but she was allowed to board.
