I downloaded an app called Vysor - https://play.google.com/store/apps/details?id=com.koushikdutta.vysor
I wanted to remove the ads so I purchased a monthly subscription - from their website. The ads got removed & it worked fine. Now I want to stop the monthly subscription after the first month is over. However, I see no option for this on the app itself to stop subscription.
In the playstore, my subscription doesn't show in "My subscriptions" - I have written to the email id given with the app and am waiting for a response. But other than that, what are my options?
