When updating either Calibre or Calibre Web, the progress of the update seems to hang and stop showing what's happening even though the update completes correctly. The problem is you don't know how long to wait and you never see the message that the old image has been deleted. Other Docker Apps are not having this problem (e.g. Trillium, Technitium, FreshRSS). Not a critical bug but very inconvenient and misleading for users.
When updating the Application, you should see the progress of downloads, pulls, and the final completion of the docker update and old image deletion so that you know the update has completed correctly.
