Hello,
on 15 August I bought dimcoins from my official Nem mobile wallet, but till now I did not recieve dimcoins. Do I recieve the dimcoins in the mobile wallet or only in the desktopwallet?
You receive the mosaics on your address not on wallet.
Is written on blockchain
You can check here if you received dimcoin and dimtoken
by typing your account address.
http://explorer.ournem.com/#/The mobile wallet has no support for mosaics yet
therefore you could maybe not see this in this wallet.
Use the latest NanoWallet for desktop. It has options to view and transfer mosaics (dimcoin, dimtoken etc...)
If you want switch from your mobile wallet to NanoWallet
export your private key from your phone write it down and save it into a secure place.
Don't loose it otherwise you are f***ed!!
After installing NanoWallet use the option to create private key wallet
then insert your key that you have copied from your phone into NanoWallet.
You should see XEM and DIMCOINS in your account when you connect to a Node.
