Android InApp getSkuDetails producing ANRs

For a game with couple of million active users, I am using InApp Billing V3 and calls getSkuDetails to load the prices of my in app items.

I do call getSkuDetails from a separate thread and still ِANRs keeps taking place.

Did anyone face similar ANRs? or Am I doing something wrong ?

And here is the ANR stack:
