This is an actual problem that I encountered myself too.
Instead of in 2min, a blockhash now expires in 1min.
Alpenglow next week will ease it a little because everyone querying for finalized commitment don't loose 10sec anymore.
still, even with the full 1min, its not enough
It's completely unacceptable that Solana transaction signatures now expire in <30 seconds now. Yall are goofy with how you treat consumer apps.
