Maybe this helps somebody: I observed the same problem, until yesterday, on my Nintendo Switch (e.g. for "THE LAST BLOCKMASTER" product): I could not purchase, because the area where the purchase amount was shown only showed the "loading animation". Restart of the game did not help. Today it was loading and I could purchase.
