Finally, after 9 days, it appears people are getting their deposits. A bunch of people (all within an hour of each other) have reported getting deposits in this thread -- a few posted screenshots as well. There's at least one other thread on AgMarketplace also mentioning deposits coming in. They all seemed to come in nearly simultaneously, if that means anything with regards to what the issue is/was.
It remains to be seen if the transaction issue has been fixed entirely, i.e. if deposits made in the immediate future are still delayed or not. Maybe someone can be a guinea pig and deposit a tiny amount to confirm.
Just letting everyone here know, though. Carry on, and upvote if you dare... 😊
P.S. To Agora, I deleted all my previous speculative posts about hacks and rogue admins. heh.
I can confirm I got mine! YES! Upvote this for visibility, please! Also, I did a test to see if it's back to normal, will update.
