Hello, I’ve successfully updated most of the Elasticsearch stack to the latest version 9.2.2

I’m having difficulty understanding how I upgrade the agent on the Fleet server; I can’t update the agent from the Fleet section in Kibana as its telling me the Fleet server agent version is behind the latest version:

However I can’t update the agent directly on the Fleet server as it tells me it must be upgraded via Fleet:

I seem to have a chicken-and-egg scenario here, can anyone help?

Disregard - the error below appears to be a UI bug, I could still press the ‘Upgrade’ button and it successfully upgraded the Fleet agent
