This growth is happening despite ~10 days of lull when Binance flooded the mempool with many transactions, which slowed the growth of channels on LN in general.

I think the growth on LN+ can be partly attributed to the fact that we launched an Umbrel app, so it's easier for Umbrel users to use LN+. For example: auto login and single click channel open.

Also, more large nodes are using LN+ to build out their network.
