Talk about sacrificing for the good of the cause! I started a chat with QBO support at 10:45 this morning, and ended it at 4:30 p.m. After about five hours and two screen share sessions, I think I got the rep to understand the problem. He said he would "contact Tier 2" about it. Half an hour after that, he came back to say that this is intentional: attached PDFs now have to be downloaded so you can view them (and subsequently hunt them down to delete the clutter). Of course they told some users that in November too, and then they fixed it with the December update. Go figure.
In the course of fiddling with it, I discovered that this time, PNG files do not seem to be affected. PDFs are behaving as they did with the November bug, opening a dialog to save the file when you click the attachment filename. But a PNG that I converted from PDF and attached to a checking register transaction displays in a new browser tab as it should. So I suppose a workaround would be to convert PDFs to PNG. That's a pain. I seldom see a "Save as PNG" option, whereas "Save as PDF" is ubiquitous. And this raises the question: If the new PDF behavior is so wonderful, why didn't they make PNGs act the same way?
Thanks everybody for contributing. I'm an unpaid volunteer bookkeeper, and I think it's time to retire.
