I don't know how to turn off an automatic Acrobat Syncrhronzer sign-in pop-up box that disconnects me from the Internet everyday. Can I read pdf without the synchronzer or can I delete the synchronizer? I have a 2015 Macbook with updated OS.
Sorry for the delay in response.
As per the issue description mentioned above, you are getting acrobat Synchronizer automatic sign-in pop-up box when trying to read a pdf in Acrobat, is that correct?
Would it be possible to share the screenshot of the issue (where you are getting acrobat synchronizer automatic sign-in pop-up box) with us? To share the screenshot here in the forums, refer to the steps given in this link: https://forums.adobe.com/docs/DOC-7043#jive_content_id_How_do_I_attach_a_screenshot
Also, could you confirm Acrobat version and Mac OS version installed on the machine? You may refer to the steps given in this link on how to check the version in Acrobat: Identify the product and its version for Acrobat and Reader DC
