Cannot delete banners

[iambernics]

Hello,

We have a DEV and PROD DevOps Organization, our user is Project Collection Administrator on both side.

When I click to the Delete button on a banner, the affected banner will be removed from the list - the Extension works as expected.

However, it will be available again after refresh the browser page on the PROD but still removed on the DEV Organization.

Have you any idea?

Is there any special permission or Organization-level settings which needed to the Extension?

Regards,
Gabor
