The release notes for 3.0.2 mention ‘Trigger tooltips only on hover’. I didn’t realise there was a problem with tooltips. However, I don’t think the hover option has ever worked with popovers. Is this what the change should refer to? Having said that, I’ve just tried adding a popover to a new page and the hover option still doesn’t work. Perhaps the note referred to something else.
I replace dmxBootstrap4Popovers.js with a version used in one of the demos on the DMX site and it works fine - but it would good not to have to replace the default file any more if it were fixed.
