1 - is this webinar started, or not?
I started a webinar this morning on my PC... but my backup co-host login (connected by 4G hotspot from my phone, running in the zoom android app on a tablet) thought the webinar was still in practice mode and wanted me to start the webinar, ie, the tablet app was offering me a hint strip saying START WEBINAR.... .     

I think this was occured because the backup co-host / tablet was in Q&A view mode when I started the webinar using the PC.

2 - werbinar title change caused login failures for practice sessions...

Last week I had some walkthroughs scheduled for this weeks webinars.   I sent out the panelist specific DIRECT URLS from Zoom - the ones where panelist have thier own unique URLs with name and passcode embded, as practice mode requires panelist logins, attendees cannot join a webinar session unless the webinar is live.

The day before the walkthroughs, the title of the webinar changed, so, I updated Zoom configuration....  I only changed the webinar title (a text field), nothing else.

When the panelists tried to open the webinar for the walkthrough practice session, the URL worked (ie it didnt say invalid URL), but, they could not login and received an error message (See below). The error message shows the new webinar title...

I resent the panelist invites (from the invite section of zoom.us) and the panelists where able to join the practice session immediately.... strange !
