When using the "Draw" feature, PowerPoint for iOS (iPad) encounters an annoying error that actually makes the feature completely unusable.
The pen regularly "slips" (every 2nd/3rd line I draw) outside the boundaries of the slide, which can only be fixed by frequently pressing the undo button and drawing again. This error does not occur on all slides but "only" on slides that contain tables.
Problem including images also described here: https://answers.microsoft.com/de-de/msoffice/forum/msoffice_powerpoint-mso_imobile-mso_mobapps/fehler-in-powerpoint-mit-apple-pencil/e3d8b8f4-6f4c-4607-a054-4e727be6de7e?tm=1529480136741
On blank slides and in other applications I have absolutely no problems with the drawing function or the pencil in general.

The option to "export pdf"works well, but the file's size is always bigger than original file. So, when I want share the pdf exported from ppt, I need acess other program to reduce it's size. Isn't a good experience.

Need a way to insert a File (object) such as a pdf into the slide.
Also need a way to allow the slide format to be changed (4:3 to 16:9).

When using powerpoint app with iOS device(I use iPad pro 12.9 2nd gen, iPhone 6s+), I write Korean letter and the powerpoint app stops. If I write English letters, the app still works well. It’s a really big problem Because I can’t make new documents with Korean language. I only can see documents been made already. I need immidiate bug fix with this problem. Some people accuse the same problem in Korean Microsoft forum. Please respond about this problem, and fix this issue. Thanks for reading.

Enable TouchID to quicken login, on all of Word, PPT and Excel, as with Outlook.

Once a user has a presentation open on their phone/tablet, they should be able to share that file in any way they can on any other device using the built-in share function (i.e. without having to go to another app/site to have the full set of sharing options their organization allows).

Need to be able to change list bullet/number color

I can insert a new comment, but no text box appears — just my name and date. I can’t edit past comments or reply to comments either.
I’ve “reset” the app through settings, logged out, and even deleted the app, restarted the ipad, and reinstalled the app. I’m on a regular ipad, not ipad pro, and the ipad is updated.

On a iphone one can import a video from the camera roll. BUT it cannot played automatically by switching the slide. That‘s a really important feature for using videos in the app.

It must be able to hide and show according to the needs of each user of the application.

Currently only one PPT slide can be printed per page. How about choosing how many slides you want to print per page?

I am using a custom font for my presentation. And it does not show up correctly on iOS.

All characters are displayed one above the other.

It did work in previous versions. And the text is still displayed correctly in other iOS-Apps (Keynote, etc.).

power point presentation suitable for DVD PLAYER!!

Just that, Add drag and drop feature in all office apps would be an improvement in the productivity

Managing with offline version with no smart art , is not possible. This is a common feature being used by all ppt makers. While travelling mobile data is always disruptive n hence non availability of this feature brings down the productivity n purpose of using ipad.

IT HAS BEEN MONTHS AND IT IS SO EASY TO IMPLEMENT. THERE IS NO EXCUSE FOR A COMPANY AS LARGE AS MICROSOFT TO HAVE NOT IMPLEMENTED THIS FEATURE YET.
