Player Chemistry is calculated differently without any squad changes

I have encountered an issue where my squad chemistry is no longer calculated as expected, even though I have not made any changes to my squad.

The same squad previously achieved full chemistry. Today, the chemistry calculation changed unexpectedly despite using the exact same players, formation, manager, and Evolutions.

I also tested replacing my striker with different players, including an Icon (Maradona), but the chemistry calculation did not change.

The issue occurs in both:

• EA SPORTS FC 26 on PlayStation 5
• EA FC Web App

This suggests the issue is not related to the Web App cache or synchronization.

Steps to Reproduce:

• Open Ultimate Team.
• Load the existing squad.
• Observe the player chemistry.

Expected Result: The squad should receive the same chemistry as before because no changes have been made to the squad.

Actual Result: The chemistry calculation is different from previous days, even though the squad is identical.

Platform:

• PlayStation 5
• EA FC Web App

Additional Information:

• The issue started today.
• Restarting the game does not resolve the issue.
• Replacing players, including Icon players, does not affect the result.
• The squad has not been modified since it previously achieved the expected chemistry.
