RecyclerView billingClient: No adapter attached; skipping layout, Sometimes it works, sometimes it doesn't

Question

first time I use billingclient, but I have a problem, by the console it gives me the error: RecyclerView billingClient: No adapter attached; skipping layout and sometimes it loads the RecyclerView and sometimes it doesn't, that is, I enter the activity and sometimes it loads it and many times it doesn't

I leave the code for an expert to guide me and I can help myself to see where I have a fault

I know that's quite an old topic but I'm posting my solution here cause I faced the same issue and perhaps it will help someone.

I don't know the reason why but I had to change my architecture. Instead of putting all the specific Billing's function call in the activity, I followed a "MVVM like" implementation. All my Billing calls are in a dedicated BillingClientWrapper class called by a BillingViewModel class that is called by my Activity. So it follows like that:

Activity → BillingViewModel → BillingClientWrapper

I used the official Billing's GitHub repo which has a similar approach: https://github.com/android/play-billing-samples

At the date of my post the implementation in the repo was done with Billing v4 and we are at v5. A bit of adaptation is needed cause some methods are deprecated.
