Usually caused by having too many positions and trying to operate on SOL which uses WSOL under the hood. The extra work that needs to be done causes the transaction to be too large.
User has a total of 6 positions. Even though they have a tiny amount of borrows, each position counts.

Confirm whether the transaction went through by using a Solana Explorer, either SolanaFM or Solscan to check whether the transaction went through. Alternatively, you can wait for a few minutes to see if your transaction is reflected on the platform. If not, try switching RPC Nodes.
Usually a ledger issue or RPC issues, refresh and try again.

It will look like this:
