weekly balancer rewards are claimable every Wednesday for liquidity provided over the previous Monday-Sunday period (So e.g. on 7th of July you'd be able to claim for the week of June 28th -> July 4th). Check the main UI or go to claim.balancer.fi to claim your rewards.
the liquidity mining reward distribution on Polygon is airdropped every Wednesday for liquidity provided over the previous Monday-Sunday period (the same as Ethereum). You do not need to claim anything. BAL is under our control, and should be reliably distributed each week at a similar time.
MATIC, QI, MTA & other partner tokens should be airdropped on Wednesdays, but these distributions are under the control of our partners, so we cannot always guarantee it ourselves. If your MATIC, QI, MTA or other expected tokens are late, please bring it up with the appropriate partner. Please wait until Thursday 00:00 UTC before raising it with them.
