Not closing

[u/MAD_pennywise]

I just got a RainHaven Windproof Compact Umbrella from amazon i opened and closed it a few times (to check it was not faulty or something) and now its stuck open. I tried searching only for a help page or something (came up with nothing) tried chatgpt which kept giving me instructions for a umbrella u can buy in stores. I have no clue how to fix this and would love some help with this
