@Daisy I should have said, mine is doing the same and still cooling but I’m unable to check that if hot flask is still hot enough if we are out and about
@Shawnee it’s a massive pain but seems to be a common occurrence with the TT goprep flask. The lid stops working after a while with the star to show if the water is hot still . I tend to take the lid off and check the water temperature with my finger
So mine has done the same but still cools down but I tend to leave it for 5 minutes to ensure it’s the right temperature for a feed
