We have 12 copies on Adobe Acrobat 2020 which are all signed in with a single Adobe account (managed by IT). We have noticed that sometimes signatures will sync between these. We have turned off 'Sync preferences accross devices and document services', but this doesn't seem to stop the signature syncing.
Hope you are doing well and sorry for the delay in response.
It is the default behavior of the application, if the user is signed into many devices using a single account the signatures will be synced across the devices.
You may try not to save the signature when creating and see if that works for you.
Hello, thank you for getting back to me.
We want to save the signature locally to the PC, but we don't want it to sync to other PCs. This should be am option.
