Hello,
Thanks for your message.
The latest full release for the 522GW is R19.9. Your mobile app has correctly identified that your dashcam was on an older version of firmware and has updated the dashcam, for you.
We do have a new version of firmware, R21.5, which is currently on staged release. This is not fully released, hence it is not currently available on all phones or computers. This is normal for a firmware release to ensure any issues are captured as soon as possible without affecting all users. If no issues are found or reported, it is then released to more and more users, eventually reaching 100%. At 100% it will be released to all platforms.
I hope this answers your question for you.
Kind regards,
Millie
