Not yet. I do not have a staging site and haven’t jumped in to try to debug this live.
One thing I plan to look at, out of sheer desperation, is that the last time I noticed data disappearing was after I received a notice that an UpdraftPlus backup had completed. Probably just a coincidence, but I don’t believe in coincidences in software problems.
I will try to give a similar and more clear case. When I save my blog the Focus keyphrase and Meta description fields are often removed. I cannot detect a pattern. It happens about once every 2 or 3 articles. Most recent occurrence just a few days ago. I completed the article, double checked these fields, since they cause trouble, and scheduled the post. They contained the correct information. When I went back and looked a couple of days later, these fields were blank. Very annoying.
