The Loading… bits are simply pricefeed, which isnt working right now.
Your “Safex…” address works to receive both SFT and SFX.
If getting from Coinspot, then the one address is all you need give them. When Coinspot completed the migration of the old coins they held, they would’ve received both the replacement SFT and correct airdrop of SFX for their coins.
It is up to them to distribute the new coinage from within their bags.
If you still hold old BTC/Omni coins in an old desktop wallet, then THE MIGRATION PERIOD IS NOW OVER
