Bug description

I have this line in my app's appinfo/info.xml:

<screenshot small-thumbnail="https://raw.githubusercontent.com/nursoda/twofactor_email/main/screenshots/select-auth_thumb.png">https://raw.githubusercontent.com/nursoda/twofactor_email/main/screenshots/challenge.png</screenshot>

I replaced that screenshot image on GitHub two weeks ago. In the app store, the new screenshots and thumbnails are displayed:

Not so in /settings/apps App's Details – there, the old image remains:

Clearing cache and reloading does not solve it.

Steps to reproduce

1. Create a NC app, do screenshots, link them with a static URL in info.xml, publish the app in the NC app store. Install the app in a NC instance. Check that images are shown in app store and NC instance.
2. Change screenshots and upload them to the SAME static URL. Check the app's details page in the store: new images are shown. Check in the NC instance: old image remains.

Expected behavior

The new thumbnails should be displayed in /settings/apps aswell.

I think the image may be cached...

[nursoda]

Yes, it seems like it, but not locally in the browser but on usercontent.apps.nextcloud.com:

This is the image URL I see in my browser:

https://usercontent.apps.nextcloud.com/aHR0cHM6Ly9yYXcuZ2l0aHVidXNlcmNvbnRlbnQuY29tL251cnNvZGEvdHdvZmFjdG9yX2VtYWlsL21haW4vc2NyZWVuc2hvdHMvY2hhbGxlbmdlLnBuZw==

The base64-encoded path part of the URL resolves to https://raw.githubusercontent.com/nursoda/twofactor_email/main/screenshots/challenge.png

So, do I have to report an issue to the app store repo?
