I ran across this limitation after upgrading to R80.10, too and contacted TAC. At the beginning, they had no idea that this feature was not working(...). At the end of this SR they stated, it will be supported in R80.20
After the upgrade to R80.20 I recognized that this feature is still not working: so I contacted TAC again.
The final answer:
"Here is the statement we received from the R&D Group Manager regarding this feature:
- The complementary log was supported in R80.10, but did not work due to bug.
- We can confirm that this feature is not supported in R80.20 and R80.30 - the sk122486 is correct.
- This feature hopefully will be brought back in next releases, but there is no concrete plan."
