This seems to be a long time issue and after going through multiple threads on this forum I came to the conclusion that most of the topics related/question asked on this specific matter has never been solved (or has been partially solved).
This solution is just for users who are actually willing to use a specific/or other apps which comes along with Creative Cloud Desktop/Services but not willing to use the Creative Cloud Desktop Service or the SYNC (even if you pause the service). In fact, there is no option to use Adobe apps without using/installing Creative Cloud but you can completely disable it/or in simple terms prevent it from bothering you.
The simple solution is to create a firewall rule and block these services. Once you block these by creating rules, you will notice that whenever you open Creative Cloud Desktop, due to lack of access to the internet it will keep on loading. I'll suggest to provide a in-human-understanble name for these rules so later whenever you decide to update your apps, you can turn off these rules under firewall services and update your apps.
Steps (only for Windows as I don't own a MAC):
1. Type Firewall in your Windows search menu and open it. 2. Under "Inboud rules" create a "New Rule". Select Program > Browse > Program Files > Adobe > Acrobat DC > Acrobat > Acrobat.exe and block the connection. 3. Provide a name and description (Provide a proper name so that you can disable this rule later on whenever you want to update your apps) 4. Do the same for "Outbound rules"
You can also create more rules alike thisin order to disable the Sync and other adobe apps if you only want to work on a specific app alike me and don't need to update/want the app to have access to the internet and fecth other details.
Removing the "Sync" option or any other application running in the background is not/never a solution in this post but atleast you never have to bother of files getting automatically synced/updating/notification/un-necessary stuffs.
Once again, I'm using this solution as I'm a student and I work with limited resources. If you are working in mass production works/much concerned about security/patches, I'll never recommend it.
Thank you for reaching out to us. We understand your concern about not syncing files with Creative Cloud. For this, you could always use Open the CC DTA and click the Cloud Icon in the toolbar (Upper right-hand side of the window) Then Click the Pause icon. It should work. Before we jump to more resolution steps, could you please let us know if you have a team or enterprise account with us?
We are here to help. It's just we need a little more information to investigate.
