Epic Store sign in does not autofill correctly or unable to fill.

Hi @DJRiful, this is a known issue that our developers are working on. I'll add your voice to the internal ticket that we have for the issue. Hopefully there will be a fix in the future.

For now, my recommendation is to copy/paste your login information to the site. Another option is to click/drag your login details to the site: https://support.1password.com/getting-started-browser/#use-drag-and-drop-to-fill-in-apps The click/drag feature is supported with the extension as well as the app.

Let us know if you have any other questions!
