We have a Frameless Online Help with Portal Skin. The help works as expected.
There is a slight slowness when navigating across the topics by clicking them in the left ToC pane. The content (topic title and body) displays first and then after a fraction of seconds the header and breadcrumbs display.
Is it something that anyone has faced and any solution for this?
Would long topic names or breadcrumbs be a reason for this delay of a fraction of seconds?
What version of RH2020 are you using? I was experiencing the exact same issue until the RH2020 Update 4 came out, which more-or-less resolved the issue. You can find my thread here: https://community.adobe.com/t5/robohelp/frameless-html-search-auto-map-0-js-taking-12-seconds-to-loa...
Also, I would suggest you open up the dev tools on your browser and see if there is anything specific that you can see is causing the slowdown.
Yes, I am using RH2020 update 4. Also, I notice some smaller projects/outputs do not face this issue they are fast. The one that faces the issue has slightly longer topic/section titles. Not sure if that is the issue. Will try Dev tools.
