Make sure you're converting your earnings into Railway credits if you intend to use them for that purpose, you can do that in your earnings page

its already enabled

ignore, i'll come back later

in the hobby plan why the remaining credits doesnt stay, thats a complete loss if its not been used

On the hobby plan, you’re not paying for 5$ credit per month. There is a 5$ subscription cost per month and alongside that you get 5$ off your usage for that month

You aren’t receiving 5$ of credit, you’re getting 5$ off your usage costs
