Timo Club App Won't Open, Blocking My Account Access

Since last night, I haven't been able to log into the Timo Club app on my phone. When I tap on the app, the page doesn't open at all, and there's no response whatsoever. Because of this, I can't access my account, and I can't use the balance or benefits within it.
I haven't tried anything like deleting and reinstalling the app yet, but not even being able to perform a basic login is causing serious hardship for me. I'm requesting that this issue with the Timo Club app be urgently investigated, that the login problem be identified and fixed, and that I be given smooth access to my account again.
