Hi,
I have been having to update my documents multiple times for library component updates and still getting the same notification about 2-3 times with every library version I receive. My teammates also reported similar repetitions so I wonder if there is a problem with component updates feature?
Hi @oes. Apologies for the late response here.
The issue you are experiencing is a known issue that we have on our radar to resolve.
Apologies for the inconvenience in the meantime. Thanks. 
I’m encountering a similar issue. I get the bell notification that a component has been updated in my library, but no matter what I do, the alert doesn’t go away. I’ve even made small changes to the symbol so I’m sure it’s updating and it is. The component update alert persists for this single symbol.
Update: So I found out what the issue is. For some reason, this symbol doesn’t behave when I apply a stack to it. I have another symbol with the exact same settings and it doesn’t cause any issues. Bizarre.
