Substance Painter 2026 on Steam not compatible with 2025 resource pack

I recently purchased the newly released Substance Painter 2026 on Steam. As the latest version, I expected it to support available downloadable resources.

However, I noticed that a free resource pack (materials/assets) on Steam requires Substance Painter 2025 to be installed in order to use it.

This raises a couple of questions:
Is there a specific reason why this pack is not compatible with the 2026 version?
Are there any plans to update it for 2026 or release an equivalent pack for the new version?

It seems counterintuitive that the latest version cannot access content available to a previous one, so I’d appreciate any clarification on whether this is intentional or just not updated yet.
