Account limits apply only for fiat deposits. 
The 1M sats max looks like an artificial restriction on LNURL only, we can bump it if needed. 
Our API allows a max of 1M USD into a fiat balance. 
Receiving into BTC balance should be unlimited (of course LN invoices are unsuitable for large amounts).

 Yes it would be great to up the lnurl restriction. 

That’s what we use at  @geyser  for generating invoices.

 Thank you for the response. Appreciate it. 🫂🫂🫂 

 We use the Maxsendable limit as a 'heads up' for our users. Would be great if you could update it to what it is 'unlimited'. 🙏

 i think it also depends on AMP support too? 

 Ok, I will discuss it internally, don't see a valid reason for 1M limit 

  @metamick the change was deployed, we will maintain a max limit around $10K
