Warm Showers Still good to contact Host?

I've been getting ready to go on tour and finally started to look at the warm showers map.
I see host on Desk top but not on the phone, am I missing something or is the phone app not working anymore ??

I also read where the site is closing or has officially closed because they posted this sometime ago ??

"In 2021, the Warmshowers board finally declared the old community driven apps a security hazard. Instead of helping them upgrade, it has withdrawn the Android app's access and blocked the developers' accounts, favouring the paid app built by the aforementioned software companies with a $20 a year subscription model."
