@AlliFlowers I think it depends on your organisation's subscription settings. Has been a while for me, but back then we had cheap subscription that forced you to make the presentation within Mentimeter, with severely limited formatting options, or you could port in a ppt but then it rendered everything as inaccessible low-res image/screenshots on to slides. Ended up flipping over to Mentimeter for specific interactive tasks then back to ppt.
