I have been using switchit for over 2 years now as my platform of choice when it comes down creating amazing webinars or training courses that are easy-to use yet very effective at delivering results! The customer service is great too - they always go above & beyond what's expected from them in terms if making sure you're happy with everything before sending out any feedback etc..
Nothing really apart form maybe some minor UI changes could be made but nothing majorly annoying either way!! We've used other platforms (like Adobe Connect) previously which were much more expensive than switching back once we realised how well this one works compared even though its not free like others around us such has Cisco Webex / Zoom/ Microsoft Teams!
