Missing handbook page referrence [Arpeggios and glissandi] from the musescore3 page
Google leads you to the musescore3 handbook page https://musescore.org/en/handbook/3/arpeggios-and-glissandi when you search for "glissando". However, the link mentioned in the page https://musescore.org/en/search/site?f%5B0%5D=type%3Abook4&keys=Arpeggi… links to nowhere and shows
"The website encountered an unexpected error. Please try again later."
However, I do find the page https://musescore.org/en/handbook/4/arpeggios-and-glissandi working normally under MuseScore 4 Handbook Notation -> Expressive markings -> Arpeggios and glissandi
Also, the search function in the side panel also shows "The website encountered an unexpected error. Please try again later."
