NWC spending quotas live on the wallet side, not the client side. Common paths by wallet: - Alby Hub: Connected Apps → find the connection → Edit → set budget amount + renewal period. - Primal Wallet: Settings → Nostr Wallet Connections → select the connection → update limits. - Amber (...

The only way I have found is to delete the application and create a new string

What do you mean by spending quota?

If you mean NWC limit, just create new NWC connection and set higher daily limit. Then update that conn string in your nostr client.
