on my site 'gesundzeit.eu' I've created a popup div with an iFrame inside (NavBar "TERMIN"). Apparently there is a problem on iOS wich doesn't allow scrolling in iFrames (https://davidwalsh.name/scroll-iframes-ios). I've tried the solution but it didn't work (I have basically no idea of HTML and CSS…).
Would be great if someone could find a solution, I've been sitting on this for hours…
Thanks so much for your help!
