Teia, Objkt, Versum and most community tools uses a data indexer to show what you mint, swap and collect. The indexer allows for faster and more complex queries than if everything was requested from the blockchain. Sometimes, the indexer lags, and when that occurs, then operations made on the marketplace are not seen, like:
The information below shows you the current status my of indexers. When any indexer is lagging or down, then you just have to wait for it to come back online. DON'T burn your mint, DON'T cancel your swap, DON'T freak out because you don't see what you just bought. Just verify that the transaction went through on Tzkt or TzStats. If it does, then it will show on HEN eventually.
