I have used Asset for a number of years & recently updated my NAS to a QNAP TS453D.

I installed Asset 7.2 but now get regular advise that Asset has no digital signature.

It will start up OK but a day later it stops with a message it has an invalid digital signature.

Error 2021-02-16 07:50:02 System App Center App Installation [App Center] Asset has an invalid digital signature. The app has stopped and cannot be installed on QTS. You can remove it in the App Center.

I can restart the app which then runs for 24hrs os so then stops again.

Is there a known solution please?
