Links to OneNote paragraphs
Teams Desktop and WebApp modify links to paragraphs created in OneNote is such way they no longer point and highlight paragraphs, instead, they just open notebook.
Piotr Janeczko commented
Create a link to a paragraph in OneNote (OneNote, OneNote 2016 or WebApp)
Paste to Teams Channel (via Desktop or WebApp)
Switch focus to another section of the OneNote or another notebook
Click on the link previously pasted into teams
One note will open but will not take you to the paragraph.
Paste the same link into outlook or Skype for business and click the link it will work properly.
Verify Teams is modifying links
