I have had problems with my R5ii in slowly waking up when it's powered down (not turned off, just in eco settings). The EVF lights up immediately but there is no information on the screen and it is insensitive to clicking buttons, and it takes several seconds to be fully operational. No-one was able to help when I posted a question some time ago. The problem has now been solved (thanks to an AI search). There is a quirk of the R5ii to check the info on both cards when waking up. I had a high capacity CF Express in slot 1 and an 1800x Lexar V60 as an emergency overflow in 2, which is never used. The V60 is the problem - changing over to a Lexar 2000x V90 solved it. It's better to have only one card in the CF slot and nothing in slot 2 than having a slower one there. Despite the 1800x being 90% of 2000x, the V60 is not up to it. I never had this problem with the R5 with V60 cards.
