I have been trying to cancel and the app does not allowing me to cancel. When trying to g to reach support the email link come back as undeliverable. I am frustrated and feel stupid as this was recommended to me and now I am stuck paying for something that does not work, will not allow to cancel or any contact information. I will be reaching out to my bank and have also reported to Apple. Wish me luck ### 1/5 — No sign up *2024-02-02* Seems to have worked well and easily until I tried to subscribe.
