That's a macOS for what I see, not a iOS version.
The reason you don't see the withdrawal is because Poloniex is still solving their issues (see bellow)
still missing my 300k sia coins.
I dont see anything solved. What pisses me off that the withdraw was open, although they knew they had huge problems with it. And therefore I withdrawed and now they are also missing.
But I read they will do a backlog or so until next tuesday.
Wallet is not solved. It says Complete, but on
https://explore.sia.tech i see only Hash not Found in Database.
To hell with such coin.
The explanation of what happens have been explained a few pages ago, so I would encourage you to always read the last pages of a thread before posting. Let's make a recap:
The price of Sia has surged x30 in the last 2 months, and so the number of users. No one was expecting that, not even the devs, so a problem with the mempool of the clients appeared. With such a big traffic and full blocks, some Tx were being dropped form the mempool to make room to new Tx. So the problem was that Polo, Bittrex an Shapeshift were pushing transactions with their TxID, but their were being dropped in their way to the miners, that have to include them in blocks. That's why it is shown as "complete" but they don't appear either at the explorer or your wallets
Sia dev team started to work with exchanges 2 weeks ago, and they finally provided them tools to handle the situation, so they could re-broadcast those Tx if dropped. Bittrex is using them admirably and they have no issues currently, not so Poloniex. Here comes the usual problems of Polo, as they have grown x10 in the last month but not their human resources to handle tickets. So they are pushing Tx of both the old clog in the network of 3 weeks ago, and also the newly generated Txs, but while some reach blocks, not so others, and they have to re-broadcast them again. And that is something they are doing slowly. Good news are that some people is gradually reporting success in old withdrawals and new, so that means that they are clearing the backlog little by little.
In top of that, Sia dev team is releasing next week a hotfix patch for all the clients to solve the handling of the mempool, so once all the users update, the issues should be gone even if Poloniex does not show to do their job properly.
So overall:
No Sia coins have been "lost", they just have to be pushed again by Poloniex, something that is happening right now. And while the original blame could be on dev team, right now it has been for two weeks on Poloniex for not using the provided tools
