Polygon Testnet (Mumbai) block number lags behind provider current block number.

[ochikov]

Hello,
I am using the multicall contract on Mumbai with address: 0x08411ADd0b5AA8ee47563b146743C13b3556c9Cc
When calling the method aggregate the block number returned in the result sometimes is not the current block number and I have to make multiple more calls, so the result in the contract to be for the current block.
The current block is taken from the web3 provider.
How can I optimise it ?

Thank you.
