Here is a strange bug. I've just published my first course in an sub-agency account of GHL. The videos I upload to the course are recorded on desktop with quicktime. The audio of the video is good. when I view the video in the course on desktop the audio is tinny - and then when i view on mobile there is no audio at all! WTF!? does anyone know how to fix ths?

If you have b2b clients, imagine the mobil app combined with this: https://ideas.gohighlevel.com/crm/p/project-management-level

At this time, PWA (Progressive Web App) functionality is not available for the client portal. Therefore, online courses can not become PWA apps either

Exactly, the Communities/Courses on Desktop, or on iPad looks very user friendly, but on mobile the are barely rudimental, not user friendly, difficult to use and many times impossible to navigate, or move between Courses/Communities/Affiliate.

This one is extremely important. Lots of people market to course creators and having a better mobile experience for online learning is paramount. Surprised this is not on the priorities list.
