So there is nothing i can do here?
What I noticed is that you are trying to send from your main wallet to Wallet 2 in the same account. Have you tried to enter any other address in
To box to see will you get the same error?
Aside from the possibility of some kind of internal bug, the only thing that comes to my mind is that the number of inputs (received transactions) is such that the price of the fee for a new transaction exceeds the total amount you have in your wallet. But if you don't have hundreds of small transactions, then you can ignore this possibility.
I am still waiting for response to the ticket from 40h....
You pay the price of using a custodial wallet, when such problem occurs, you have 2 options - to wait for their response (it can be 1 day or 10 days), or to use the seed to recover your wallet through another program (wallet).
