<![CDATA[Latest Opera produces error 431 consistently]]>Been using Opera One for a very long time and it's now forcing me to go back to Brave Browser.
It never used to give error 431 forcing a cookie clearance to fix.
Version is 132.0.5905.73; Mac 26.5.1 M1
Reinstalled an earlier version that fixed the problem but the auto-update reintroduced it as i hadn't used the terminal inhibit update.
Tried the terminal update no fix, it updated, 431 returned.

Just use link on any other Browser, reload it, no problem. Opera gives 431 even on my banking sites that it NEVER did.
