I think we may be talking about the same thing.
The notifications - such as intruders, city connected, trade routes destroyed gets hidden behind the bar of icons that you can click on such as new things to build, new science, new upgrade etc.
If the scoll bar of notifications is partly hidden behind the "action" bar you cannot scroll it.
I think it is a bit annoying as some of the decisions I need to make about what to do may depend on those notifications
However, if your issue is different maybe post a picture
