I was directed to speak to the Global Service Center today after I submitted feedback yesterday. The feedback email asked me to call GSC. GSC could not get the latest PDF to open either. So apparently it is not a cookie or browser issue. Others here on the tech page had problems with the temple recommend change PDF's when they were first uploaded as well. A church employee reported the same thing with multiple machines, trying over and over. Please see this link:

My guess, the PDF's are either corrupted or incorrectly uploaded due to new personnel, new software or some other issue. and then are not being checked on the LCR web page after they are uploaded to see if they work. Meanwhile older PDF's open just fine.
I have decades experience in catalog production with PDF's. 3 of the last 4 PDF's on the Official Communications page have had this problem and I clear my cache and cookies frequently, am using the latest version of Adobe, and I often see the links way before the email blast goes out to leaders about the bulletins being available on line. I just checked, the latest bulletin about the scriptures in Swahili which was posted 4 calendar days ago still says please try again later.
Perhaps indeed the proper permissions are not being programmed prior to the bulletins being uploaded but are done on a trailing basis, why that would be, heaven only knows. However, I can also open older Official Communications PDF's which are not specifically targeted to me by calling, so that does not make sense either.
