We're seeing the plugin crash the browser (Chrome and Safari) on iOS for many users.
As an example, click on the first item under header "De Vlaamse Jager Archief (gratis)" on https://hvv.be/vereniging/de-vlaamse-jager/
It reloads around a second after loading and does this once or two more times before crashing.
I just upgraded to the newest version on Gumroad, and it's still happening unfortunately.
