Teams Presentation Share not possible in a huge member meeting

Question

Good day,

Last Wednesday, September 23rd, 2020 I had a virtual event about teams with my iPad.
The rehearsals in advance all worked very well. During the event, however, I no longer had an icon to share a PowerPoint. I couldn't share the screen either. (In the upper right corner of the iPad, where it was done a few weeks ago, it didn't work either!)

My colleague at the iPad then had to share my presentation so that the participants could see something.
After the event, when there were only about 10 participants left, the ICON "Share" suddenly appeared again .....
I would like to know how to work around the problem for other events and why that didn't work.
I went out several times, shut down the iPad completely, went in through my event and later also through the participants' link. Nowhere could I share. In the options I had set that everyone can present. Otherwise my colleague wouldn't have been able to ...
It would be nice to receive feedback to save others from doing so.

iOS 13.7. Is installed
There were about 100 participants in the VA, the "Share" button was not available. Only when there were only about 10 people in the meeting was the "Share" button visible again.
The button was available for one colleague from the start, but not for another colleague.

Hi @Vadim Chernyavsky

Does this issue persist all the time?

Can you share screen normally when you use Teams web App?

According to your description, it seems this issue is happened when multiple attendees join your meeting and only part of uses met this issue. So if you share screen with 10 attendees first then invite multiple users to join your meeting, can you share your screen normally?

In this case, we recommend you try to clean your client cache file and update your Teams client version to see if this issue can be fixed. For more details about how to clean client cache file, you can learn it from:
