Amazon Shipping Setting Automation (SSA) – Increased FBM Transit Times?

Hello fellow sellers,

I've recently noticed that my FBM shipping transit times have increased from '2 to 3 days' to '5 days', and it appears Amazon's Shipping Setting Automation (SSA) may have updated the transit times automatically. I haven't made any manual adjustments to my settings. I use Evri and Royal Mail, so I'm unsure if this is affecting other carriers as well.

Has anyone else experienced similar changes?

Would appreciate your insights and any suggestions on how to address this if it’s affecting your listings.

Thank you!
