Wrinkles on the walls

[Meyarae13]

over the winter our pilllow had went flat but couldn’t do anything about it and so when we opened it last week we noticed wrinkles on the sides of the walls the liner is straight on the top and the pool was professionally installed in June 2021 .
Please help

Welcome to TFP.

Some folks try and use a toilet plunger to pull wrinkles out of a liner.

What type of pool is this?

Give us some pictures of the overall pool area.
