I have been using this app for awhile now with no problem,recently I lost my phone and needed to update my cell number. So I was able to verify the first part of my F2 security verified my email and all and they still wanted me to verify a number that I was trying to change*** Then I was told to send in a copy of my ID and holding a paper with a code given from them on it I did all that Then they told me that I have a duplicate account already with the number that I am trying to change to.Bittom line is they Hold your account when the market makes a big drop or Bull Market. I am not even making a withdrawal and the are using BS tactics
