No + add block symbol since upgrade to wp 6.6.

 I upgraded yesterday to wp 6.6.1. and latest version of my theme, SlimClick Pro child.

Since then, if I want to insert an Envira gallery between two paragraphs, I no longer see the + sign. I have spotted a + in the menu at the top and can then select envira. But it puts the selected gallery at the bottom of my post rather than inserting it between two text paragraphs (eg between paragraphs 4 and 5 in the sample post I have linked to).

I’m trying to work out what has happened. I really don’t want to understand more than I need to as my site has worked perfectly happily for several years. Any pointers would be very welcome.
