Greetings to all the experts.

I have the following problem, I have implemented Billing Subscriptions in Android, the code works well, the problem is that the Recyclerview sometimes loads and many others it doesn't, sometimes it loads first, sometimes you have to enter the atricity a few times, I don't understand why it makes that bug, if you could check the code and guide me I would appreciate it

suscription.java
