How it works
Run checks one by one. Allow media or sensors only when you choose Start. Skip unavailable devices, return to a previous step, retest after a fix and download a local report.
What this means
Browser observations and your confirmations are recorded separately from unsupported or untested checks. No overall health percentage or application compatibility is promised.
