App Engine: Static Files Not Updating on Deploy

Question

I pushed an HTML static file containing an Angular SPA as catch-all handler for my custom domain with this settings:

- url: /(api|activate|associate|c|close_fb|

2020 Update:

For my application I found that App Engine started failing to detect my latest app deployments once I reached 50 Versions in my Versions list.

See (Burger Menu) -> App Engine -> Versions

After deleting a bunch of old versions on next deploy it picked up my latest changes immediately. Not sure if this is specific to my account or billing settings but that solved it for me.
