I'm having the same issue. Publishing a SCORM 1.2 using the January 2020 version of Storyline 360 (version 3.36.21289.0) my projects bookmarking works fine.
Upgrading Storyline 360 to anything newer loses bookmarking after the user gets to some slides with quite a few user entry texts. This is across two completely different project files.
My client's LMS does not accept SCORM 2004 files, just SCORM 1.2.
If the suspend_data was working fine before then it isn't anymore since after the 3.36.21289.0 version.
Something has been broken and I'm now stuck with the January 2020 version and can't benefit from any new features/bugs fix. Digging through the log change should highlight what was changed. This needs resolving...
Many thanks.
