@tuanphan Hello, I am trying to troubleshoot a similar problem-- using anchor links for fluid engine sections. I used the suggestion you made above which worked great for same-page anchor links to fluid engine sections, but it doesn't seem to be working when I try to link to the specific section from another page.
For example, on the specialties page (https://orka-c1-sep.squarespace.com/specialties) I added a code block to fluid engine section "<span id="mood"></span>"
The button at the top of that page works with the link "#mood"
But to link to that section from the home page I added the link: https://orka-c1-sep.squarespace.com/specialties#mood , which doesn't work.
Any suggestions are so appreciated!
