Hey kteirvine, thanks for reaching out on our help forum and for your question.
We'd like to advise that you're right to suspect the flashing lights may be indicating an update has been sent to your equipment as we usually perform those during the least social hours.
Sorry if that had you worried, please rest assured that this is 100% normal and if your TV service is working ok there's nothing to be concerned about.
in case you experience issues in the future we'll be here to help and advise further.
Best regards,
Adri - Forum Team
