ICP daily rewards (maturity) low?

Hi everyone,

In the last while (2 weeks for sure, perhaps longer) my daily maturity rewards have been about half of what i am typically receiving - I was wondering if anyone else is experiencing this and what might be causing it?

For context, I have a Voting Power: 1’574.35, with around 720 ICP/maturity in my account. I am staking for 8 years and have never dissolved. I started staking 3ish years ago with a small amount of ICP and added periodically, thus my age bonus is currently 9%. I have ensured my neuron is active (178 days left) by confirming my following.

Last week, i was following one neuron labelled “28” which for all voting topics, i thought perhaps they could be missing votes causing me to miss rewards, so switched all the topics to the Dfinity Foundation, but still continue to have lower than anticipated rewards. According to both my calculations, and the information on the dashboard about my neuron (view on the dashboard yourself @neuron 1656498880017986955), i should be earning 0.29 Maturity a day, and currently i earn about 0.13.

Anyone have any insight or advice for how i can get to the bottom of this and gain my correct amount of rewards? Thank you in advance.

It says neuron not found.
Do manual voting, if you managed to stake this much, it dont hurt to log in and vote each day.
