It does'nt allow me to link more than one device to my Uphold Wallet

The instructions as set here should be able you to check which is which: Unable to re-verify wallet - #118 by Mattches

But this is when you still have access to those wallets, however, this is not to be your case. I suggest that when requesting, just instruct the mods or whoever you are in contact with following the link above to remove everything… Then you just have to re-link everything from your new devices.
