Ensure the lid is fully sealed and that the vacuum seal has not been compromised. Pre-heating or pre-chilling the mug with hot or cold water for a few minutes before filling can also improve performance.

Check for any obstructions or dried residue around the lid seal. Clean the lid and the rim of the mug thoroughly. Ensure the lid is aligned correctly before attempting to close it.

Verify that the lid is completely screwed on and sealed tightly. Inspect the silicone gasket on the lid for any damage or debris that might be preventing a proper seal.

This typically indicates a compromised vacuum seal, which can affect insulation performance. Contact customer support if this is a persistent issue with a new product.
