activating zoom links on my iPad takes me back to my home screen

Has anyone else experienced the above? Whenever I activate a zoom link on my iPad it throws me back to my home screen and doesn't activate the link. I do not have this issue on my iPhone.
My iPad is an iPad air2 running ipad13.5.1. Any ideas why this is happening? Zoom is also up to date.

I sometimes get dumped into Safari.

Usually the Zoom link is the wrong one, and the only thing I can think of is to go on Safari and clear tabs, but they still open up in Safari. Other Zoom links work the way they're supposed to.
