Photoshop Plugin still shows “Compatible app required” despite lowering minimum version requirement

Hi everyone,

I’m investigating a compatibility issue affecting my Photoshop plugin, Lipika.

Users reported receiving “Compatible app required” in Creative Cloud Desktop even when their installed Photoshop version appears to meet the declared requirements.

To address this, I republished the plugin and reduced the minimum supported version:

• Previous minimum version: Photoshop 24.2.0+
• Updated minimum version: Photoshop 24.0.0+

Goal: Support Photoshop 24.0.0 and newer (including latest releases).

However, the issue still persists.

Current environment:
• Plugin: Lipika (latest published version)
• Installed Photoshop: 27.4.0 Release
• Manifest host.minVersion: 24.0.0
• Creative Cloud Desktop still shows “Compatible app required” and suggests installing a newer Photoshop version.

I’ve attached:
• Compatibility error screenshot
• Installed Photoshop version screenshot
• Manifest configuration screenshot

Questions:

1. Does Creative Cloud Desktop cache compatibility data after publishing updates?

2. Is compatibility determined by Marketplace settings, CCX package metadata, or both?

3. Is there a way to inspect the final compatibility metadata Adobe reads after publication?

4. Could Creative Cloud Desktop or UPIC still be using older package data?

5. Are there known cases where Photoshop version detection fails?

6. What is the recommended way to validate compatibility before release?

I can provide the CCX package, manifest, screenshots, and reproduction steps if needed.

Thanks for any guidance.
