@leocg Do I reword this? The title? All other guidelines on the list have been done, with the exception of versions and platforms. Thank you

What's missing in your report is any detailed description of what specifically happens when attempting to use Opera for virtual schools (ie: "unable to view" provides almost no troubleshooting details... hence, do they receive/send audio successfully, do they completely fail to connect to the sites involved, do they get error messages, etc, etc?). Also missing is a list of the specific "types of video platforms" involved, as well as what version(s) of Opera are involved. Finally, have you (or any student) tried the problem isolation methods listed in https://forums.opera.com/topic/43601/instructions-on-posting-about-problems-in-opera-for-windows/1 , and if so, what are the results for each of those items that have been tried?

The object in all this is to enable a helper here to try to duplicate your problem or deduce from your details what may be actually happening. Given that other browsers "work", it seems most likely that there's some setting or functionality (eg: its adblocker) in Opera that's blocking the virtual school from operating correctly. The key is to find out which one.
