The pram part of the travel system will not lay flat due to the side mounts not coming down parelell to the clips on the frame, there is no movement and I can’t use this as a pram.
And what is your question? Your problem seems to me as you should claim warranty/ask the seller or the brand's customer service for help. To make the side mounts move, btw, try to pull the rear lever completely up, adjust the sides to what position you need them to be; and if that doesn't work, something is wrong with your pram, and you should not use it until it is repaired. Wishing you the best of luck!
