First, ensure you are importing the correct file. In the case of the sticker book, confirm you are importing the file labeled "sticker book". It is a special GoodNotes file, not the standard .zip file containing all of the sticker PNG image files.
Second, make sure you are following the import instructions on this page.
If the import instructions are leading to an error, try the following:
1. Try importing the file into GoodNotes directly from the Google Drive folder or portal where your files were provided, do not rename the file or save it to your local drive/iPad first.
2. Force close Goodnotes by swiping up to close it from your multitasking view (support.apple.com/en-us/HT201330). Reopen GoodNotes and try to import the file again.
3. Check to make sure your GoodNotes app is updated to the latest version
