I am creating my first Gig in FIVEER, but for some reason I cannot enter a "delivery time".😱😱😱 I select the date from the pull down list and enter it, but an error occurs and I cannot proceed to the next page. The reason for the error is 「This option is no longer supported. Please select a new delivery time.」 I have tried the options from 1days delivery to 90days delivery, but I get an error and cannot proceed. Is this a bug in the fiveer site?
