Hello skripp,
Works fine for me
Interesting.
seems to be website specific. For example,I can’t zoom on zhihu, cn.nytimes.com, xinhuanet.com, taobao and jd.
However, for example Zn.Wikipedia.com, google and a lot others work just fine.
tried the same links in safari and they all can zoom just fine.
tried on iPad Air 2 and iPhone 11 (14.3 and 14.6 respectively). Latest version of Pleco.
