Been diving for a long time but I can't help but say... When you encounter a wallet/board data suddenly "lagging," many times it's not necessarily the chain being congested. On-chain data needs to be first indexed by an indexer, then fed into a query layer like a subgraph. When you click, you're actually asking for a "organized ledger." Indexers need to queue, replay blocks, and sometimes can't keep up with the latest blocks; plus RPC rate limiting (basically, the interface is overwhelmed), which results in sometimes fast loading and sometimes spinning. Recently, new L1/L2s are incentivizing to pull TVL, causing a surge of users. Old users complain about "mining, liquidation, selling," which I understand, as the backend request volume also explodes... Anyway, when I see lag, I wait first, don't immediately suspect that your authorization or something else went wrong.
