Troubleshooting a 429 API error and running columns repeatedly

Hi legends! Question when I want to run a column I often get the error Clay received a 429 error from the API with Content: Unexpected token T in JSON at position 0 I understand that there is a cap regarding the amount of records you are trying to pull via the API. But two questions:

1.
Why do I have to re-run these columns over and over again? Isn't there a simple way that you can select a column and let it re-run untill everything has run (e.g. in the background)?
2.
Normally every hour I can re-run the column, but for several hours I keep the same error code. Bug?
