i never had that problem even on bitcoin and ltc withdrawals. maybe there are currently some issues, try to send a support ticket and your problem might get fixed asap
Maybe it is because their newly opened signature campaign, since they use their own wallet to directly pay their member, it is possible such change caused a traffic on their system.
Dear admin, I've got the interest from 24hr deposit, it works smoothly, everything goes perfectly. Thank you.
I dont think it is happening due to sig campaign but the one i see it is just a bug on smart phones? Maybe thats the decent we can call that and only OP can clarify the issue because if that really happening i think he should really try to fix that so the smartphone users can do smooth trades and withdraw easily their funds.
