Make sure you CONFIRM THE EMAIL before clicking COMPLETE on the 1st screen that pops up after a successful withdraw.

I successfully withdrew TRI a few days ago.

Then I had a withdraw error and those coins became frozen.

After seeing this thread I rushed to withdraw my available coins and they withdrew without any issues.

The difference between the error and successful tranasaction was that I avoided the "withdraw confirmation success pop up" altogether and went directly to my email to confirm there and then follow the prompts.

Perhaps this is simply a UI/UX issue from a brutally unclear withdraw process?
