Understood. So if I don't use the advance sending, how will my reserve become liquid? is it a matter of time or is there anything I can do? All my balance has been in the wallet since 2017, although  if I click on details I see this information:

Received:
Date: 07/26/2020
Label:
Amount: 2993.9
From: BHu6JNUZSRa8zKQEq8JpyjUdGwKLVvDQag
Liquidity Rating: 543 (Good)
TXID: bbdf83494dbcd563975d3cb5d089ea4678b154017fa3c95f857e4a694b415857:1

But the block explorer shows that transaction as from 3/29/2017, 11:37:04 AM (UTC+2:00)
