… does a userAgent test* (oops), then checks for TouchEvent. In any event, modifying our browser detection code this way solved the problem for us. The !window.MSStream is in there because Microsoft injected “iPhone" into IE11’s user agent on Windows Phone. (Does anyone use Windows Phone?)
Note that the console.log line can be removed if you like. Ron > On Mar 7, 2020, at 1:32 PM, Ronald Rosell <[email protected]> wrote: > > Tom, > > Here’s how we handled it.
