"Gotten" or "received" (past participle of "saama").
Here, 'saanud' is the past participle form of the verb 'saama', meaning 'to receive'. It is used in combination with the auxiliary verb 'olen' to form the present perfect tense.
Ma olen saanud teie sõnumi.
I have received your message.
In this example, 'saanud' still represents the past participle form of 'saama', used to indicate an event leading to understanding.

After the training, I have better understood my mistakes.
Here again, 'saanud' works as the past participle of 'saama', forming a negated present perfect tense with the auxiliary verb 'pole' (not have).
