This is probably the difference between buying the coins on Uphold and withdrawing is less than 24h.
Please wait 24 since last attempt and withdraw then and let us know if all things went fine or not.
You mean you sent dash toward the dash wallet right?
Now you wnt to take them back to fiat (euro, dollar etc) right?
If so you must open the account on an eschange like kraken or uphold or bitfinex or whatever excahnge which support the fiat pairs.
Send coins ther after verified sell and withdraw to your bank account.
As I said, wait 24h and try again.
Please try again, it should work now. If not, please open a ticket, send a screenshot of the error, and we will get this solved formyou ASAP :).
Can we ask you to rise a ticket toward the firstname.lastname@example.org and attaching the logs from your android app?
To do it, simply send us a report via your app.
Having the logs let us have an idea why this issue occurs.
