PowerPoint "View - Presenter View" shows "truncated" "<Slide x of y>

To admins: it has taken hours to post this message. I got "Correct the highlighted errors and try again", but no highlighted error was shown. Eventually it reported that at least one label should be chosen. I selected PowerPoint, but still got the dreaded "Post flooding detected (user tried to post more than x messages within y seconds)". And so on for hours, even after waiting long times before clicking the Post button. Also, I got the bogus message "Your content was last saved to auto recover at xx:yy AM. Please save your document, using the save button, regularly to avoid data loss" (yet no such Save button shower ever) again and again, even after selecting to discard it because I actually did not have any draft saved ever. I have just registered to post now. Really FRUSTRATING!!! Using Safari 16.3 (17614.4.6.11.6, 17614) on macOS 12.6.3 (21G419) Monterey on Intel x86 iMac. I could finally post it using Firefox. But the edit option deleted all double carriage returns to separate paragraphs, so I had to enter them all again. FRUSTRATING!!!

Sorry if this is not the right place to send feedback-issues-flaws-bugs to Microsoft via web, but I could not find other.

As explained in the link below, PowerPoint "View - Presenter View" shows "truncated" "<Slide x of y>" (only upper part of "Slide 1 of 10" for instance is shown):

It would be great if that could be fixed. Thanks!
