Transaction not being relayed by nodes or confirming in blocks?

[Liquid71]

I have a withdrawal from Polinex to my local wallet, Armory running as a full node. Armory doesn't even show the transaction as pending which I've never seen before, and it's running as a full node with 12 connections last I checked. Their is a transaction fee paid, and the transaction shows up on blockchain.info and blockexplorer.

I had armory rescan the database and the pending transaction doesn't show up. Also no idea why it's still pending and not added to any blocks since there is a transaction fee.

Anyone know what's going on with those two transactions. Any other info I could provide to help just ask. I submitted a support ticket to polinex, but I'm super confused what could be going on. I'm not super technical with Bitcoin but understand the basics, or at least I thought I did..kinda stumped on this one.

Is it possible transaction went to blockchain.info but not the rest of the network, and blockexplorer.com just copies data from blockchain.info? Or maybe I understand less than I thought and somebody could shed some light on this for me, thanks.

Just wanted to add I rebuilt and re scanned databases on Armory and didn't change anything. So is the transaction being blacklisted by nodes or something, or just never actually got broadcast to the network but somehow ended up on the block explorer websites?

I see there is a backlog of transactions, would that be the reason the unconfirmed tx isn't showing up in my local wallet?  I'm not worried about the coins or speed, just thought if the tx was broadcast to blockchain.info it would show up in my wallet. Even during the "stress tests" I never saw a tx not show up, so just confused and curious. Would nodes hold back broadcasting a tx if there was a backlog so my node just hasn't received it yet?

Sorry for the naive guesses, just thought I had a laymen understanding of the basics of how transactions are broadcast and once propagated around the network it was just a matter of a miner finding a block and including the tx, and this one makes me want to learn more since I can't figure out why it the unconfirmed tx wouldn't show up on my end.
