Hello Expert,
APEX 20.2
The checksum computed on the request, clear cache, argument names, and argument values
(,,P1_NEW,1 [vBPscpQtHiFXrqJ0o9PZ8qvLgkWfdh8azY6-Q2hT8oe0dafMlFg4y9d2gpvoi47qZJsR2BSZU3BEg2cX9AAglw])
did not match the checksum passed into the show procedure (O4tEKqqNshNm-eTpEOfI55FFz0YtId8eQfPnTVaO5I3wrlftXQKwXHDG7oqYoIYNc_R8egYx7xGr8-ihkWhF7w).

apex_error_code: APEX.SESSION_STATE.SSP_VIOLATION2_FOR_DEVELOPERS
component.type: APEX_APPLICATION_PAGES
component.id: 10100000000
I got this error when redirect to a page that has "APEX_CLONE_SESSION" in request and the URL has items. Page Access Protection for this page is Arguments Must Have Checksum. It worked fine when we were in APEX 19.2. I tried to set Friendly URLs of the application to Off and it works fine**.** Also, I had demonstrate this on apex.oracle.com and it works fine.
