Flying domestically in China on a 60-day automatic visa extension – resolved!

Hello, I asked a question about a week ago and I just wanted to give an update on what actually happened to help out anybody in the same situation.
Flight from Shanghai to Beijing: check-in counter nobody even looked at the visa, no problems
Flight from Beijing out of China: check-in counter nobody looked, immigration counter took a little bit longer because they had to call their supervisors I assume because they saw my visa was expired, I didn’t have to give my explanation that I still fell within the 60-day extension, they stamped like normal and I was on my way
