Troubleshoot an upload or storage-limit error
Uploads can fail because the file exceeds the per-file limit, the account storage allowance is full, or the current member does not have editor access.
Check Plan & usage
Confirm the remaining cloud storage and the account plan.
Check the single-file size
Free currently supports up to 25 MB per file. Pro Lifetime currently supports up to 250 MB.
Confirm edit access
Viewer access cannot upload into content that requires editor permission.
Retry after the current upload finishes
Do not start a conflicting save or navigation while a large upload is still finalizing.
Contact support if a valid file still fails
Include the file type and size, but do not email sensitive file contents unless support specifically asks for a safe diagnostic.
If the quota looks wrong after deleting files, reopen Plan & usage so NoteTunnel can reconcile current references.
