Why am I unable to share my zApp Book to the sQuizya Library?
If, in Step 3 of the zApp Book Creator, the options to share your zApp Book to the sQuizya Library (teachers only) or sQuizya Library (all users) are unavailable to you, it means that you have imported a question or zApp that another user has protected by copyright into your own. Even if you significantly modify the question(s) or zApp(s), they retain the copyright tag of their original author(s).
zApps with copyright restrictions can be freely reproduced, modified, extracted and shared into another zApp or zApp Book within the sQuizya platform, but to protect the copyright of the original author, your resulting zApp or zApp Book that utilises any portion of the copyrighted zApp are barred from being published outside of your institution.
