Again and into the future THANK YOU for keeping us Sony users (and others) up to date with updates to all things. This issue not seen or aware of by many, I for one. You have shared so much about Sony cameras since the beginning of the Sony A7 line with books (yes paper) found in book stores (back in 2013 I still have and study often). Those books have tricks to learn from and try to do even with todays, so called best of the best cameras.
Thank you Ed. It’s a bug that only pops up with one particular setting, yet it’s nice to see it addressed.
