SUMMARY
Inline annotations are not properly saved to be visible in (some) other PDF viewers. related to https://bugs.kde.org/show_bug.cgi?id=353400

STEPS TO REPRODUCE
1. Open pdf file
2. Press F6 to show annotation tools, select Inline Note. 
3. Add some text
4. Save pdf
5. Open pdf in other viewer 

I tested Google PDF viewer on Androd and Microsoft Edge on Windows (being the default preinstalled tools most people use on other systems). I remember once having the same issue with Adobe Acrobat, but couldn't test it now.  

OBSERVED RESULT

The inline note is ignored. Other annotations such as freehand line and text markup are shown properly.

EXPECTED RESULT

The inline note should be shown. Alternatively, a subtle notification should appear to user that inline notes are not compatible features (e.g. when hovering over inline note icon in the annotations toolbar). If I may add here, to improve UI and usability, the same goes for the stamp tool. For stamps is stated under Settings, Annotation options that "stamps inserted in PDF documents are not visible in PDF readers other than Okular" but this text should be shown to user when they are up to use it.

Okular 1.9.3 using Poppler 0.77.0

Adobe Reader DC on Windows shows both annotations for that file you attached.

To me says the bug is mostly probably on the other viewers not showing things correctly.

Anyway if you're convinced this is still a bug, it's not really a bug in Okular either since Okular doesn't do any PDF writing, that's done in poppler, so if you feel like poppler could try to somehow write "better" PDF people open a and issue in the poppler bug tracker.
