PROOFSTAMP TROUBLESHOOTING
Toolbar icon greyed out: ProofStamp can't run on chrome:// pages or the Chrome Web Store itself open a normal website tab.
- Nothing downloads: check Chrome's download permission prompt and try again from the preview screen.
- Key rejected: copy the full key from your Gumroad receipt email, no extra spaces.
MOMENTNOTES TROUBLESHOOTING
Button missing: MomentNotes only appears on youtube.com/watch pages reload the page once after installing.
- Notes missing: notes are saved per video. Open the same video again, or check the toolbar popup, which lists every video with notes.
- Download blocked: check Chrome's download permission. Copy Markdown always works even if downloads are blocked.
