Hi,
Do you have a link where WPLMS 4.x documentation is published?
The Quick Help links in the footer of WPLMS.io are all broken. They all point to: https://vibethemes.com/why-we-should-switch-to-progressive-web-apps/
https://vibethemes.github.io/wplms-docs/index.html has older documentation
Please share 4.x documentation link
