Lightning Network Channels Question


Yesterday I set up 2 lightning channels. One was an outbound channel for 1M sats. The other was an inbound channel for 1M sats.

This morning I purchased 720k sats using RoboSats P2P network. All went well (and sidenote was an incredible first experience with this). Now I noticed that my inbound capacity has been lowered by the 720k sats that I purchased. IE - my inbound capacity is now 280k from 1M.

My question is, will my inbound capacity go back to 1M eventually? I want to better understand why it was reduced and just generally how these channels work.
