I just stumbled about this thread about the docker image of the openHAB cloud. After a quick look on GitHub I also saw that the last release was in march 2019 as mentioned in this thread.
Since that release in march 2019 some fixes were merged. One of those is PR #256 which might solve a problem concerning delayed notifications which some people are experiencing.
Since I’m personally experiencing this problem I asked myself when the openHAB cloud (myopenhab.org) will be updated to fix this problem.
Is there some kind of release cycle when the openHAB cloud will be updated / a new release will be released and deployed?
