Thank you so much for your reply. So, just to be on the same page, you're saying once the "send coins" button is pressed, an immediate uninstall (I did not immediately uninstall but it was very soon after) would not affect the transaction? That's great news. Hopefully we can figure out what went wrong where, hopefully there is still hope for the coins! Again, thanks a ton knightdk
Yes this is correct. The moment you commenced to send those coins from that wallet
they where put in to chain and are on its way to recipient.
Maybe you remember what was that app's wallet address? If you do, try to check it with
any block exploring site. blockchain.info etc. There you may find why its taking so long to process this TX. I bet it was low fee...
