How do i make sure a certain address is attached to Tangle and how do I attach it if it is not attached (as i see a new receiving address now)? For instance, I sent a few IOTAs (Mi) from one wallet to another with the following recipient address FUTOOUZXF9O9ISLDOR9VRUKOUASCBJGPJAIFVDXKE9IINTIFJCSVRXBRETLTOMKNNVZCOIZVWAWUNMFVZZRZXSOSEZ
While https://thetangle.org/ confirms receiving the transaction, it does not show in the wallet history as pending. This has not been the case earlier.
