I have the same problem with linda. Staking does not seem to work as it should. My wallet was taking since 21.08 and I got onlu about 280 linda once.
Whole the time on the left corner I got information that reciving coins will take some day. Once it is 2 days, once 1, once 3 but there is no staking.
Please reboot your wallet. Make sure you have Thousands,hundreds of thousand or millions Linda in your wallet to able to receive staking reward. Your reward is proportional to the amount of coin you are staking. You should not stake 5000 Linda and expect to be getting 1000 Linda everyday, is not possible.
