When opening the "Cropping and Straightening" topic in Affinity Photo Help, I get a Javascript error in the tabbedimages.js file. I am then unable to access any of the tabs in that topic.
This error also happens when accessing the Visual Reference help topic.
NB: Running the Affinity Photo Help system manually from a Google Chrome browser or Microsoft Edge browser window does not encounter this problem.
Windows 10 Pro (1909)
Affinity Photo 1.8.3.641
