Having similar problems. KEPLR shows my assets OK & my LP staking tokens, but cannot access any of these to claim rewards (other than those of staking SCRT), swap, re-earn or withdraw. On chrome originally but unable to claim. Moved to Brave & for a bit worked OK. Then suddenly came up with ‘wrong viewing key’. Now moved back to chrome (with spending for third time for viewing keys.) Still no joy. Checked public keys & they are all reflected in KEPLR wallet as the same, so can only conclude it is a network/congestion issue??? We need a bit of feedback from the developers please??
