Pro does not open offline
Reconnect, open Pro once, wait for the library to load, and then reopen the installed version. Browser private modes may not retain application data reliably.
A PDF disappeared
OfflineReady cannot restore files removed with browser data, application storage, or device cleanup. Re-add the PDF from your retained original.
I changed devices or browsers
Libraries do not synchronize or transfer automatically. Open Pro on the new device and add PDFs from their original files.
I forgot the app-lock password
The lock is local to that browser. Contact support for current reset guidance. It is not an encryption password or cloud-account credential.
