I have the same issue. It says COMPLETED by Bitfinex but the amount is not showing in my iota wallet light.. When i click on the link provided by Bitfinex i see that the transfer confirmation status by Tangler.org is set to FALSE.. What hash shall i provide you here so that you can see what i am seeing also? Trunk Transaction Hash, Branch Transaction Hash or Bundle Hash?
Also, can u provide the link to Bitflinex Slack channel?
Thank you in advance..
