This morning I return to continue the investigation on Note-3 with corrupted data; the device has been left idle since the day the issue was raised. I found that the corrupted fingerprint is actually get updated with the correct value @ with last activation timestamp:
Saturday, 6 February 2021 06:42:43.052 [GMT+08:00]
peacock@atalk.sytes.net:717642636 79bed1b1f972d8db9b0e3ca9cce81b4952002e252cc6ba8486d4c94b44e33c4c.
In checking the debug log, found that smack-omemo has proceeded to update the fingerprint after received the requested bundle from the server. Look like smack-omemo has built in a mechanism to do the repair after some inactivity period has elapsed.
