Surprised to be the one to start the thread 2 weeks in a row but I have 3 answers that I am certain are correct but I just can’t parse!
23d Maybe real prevalence (8)
I have CURRENCY (prevalence) but the cryptic bit?
47d This increase could cause tantrums (4,2)
Must be STEP UP (increase) but why?
49a Army officer appointed bishop, gradual development. Political earthquake (7,10)
Must be OCTOBER REVOLUTION with EVOLUTION being gradual development. But the rest has baffled me!
Apologies if I’ve overshared on a prize crossword. I never enter but I do enjoy them!
