We had an error happen with our portfolio workapps program where it was provisioning workapps but not linking them to the projects. We tried to remove the workapps by deleting the projects from control center, but they stay in the portfolio workapp and just show errors when you try to open them. The way we get around having multiple project workapps is simply renaming the shell or unlinked workapp something like "xxx Error Workapp Can Not Delete". It would be great if we could just flat out delete the workapp.
Portfolio WorkApp has a lot of issues - especially with archiving and deleting.
We are having the same issues - I'd like a response from Smartsheet on this please.
