Question: Why have it not yet proposed another update? Nothing is listed also after i select refresh.
Just to try something, I turned on
Settings > Developer Options > Use Staging OTA server
And then it lists two updates to /e/OS 0.18 from 2 and 14 August.
According to Week 33 : Development and Testing Updates, 0.18 was OTA released Aug 19.
That one have a bug for FP3, resolved by an update in staging others are testing, but my phone fail to see that also. https://gitlab.e.foundation/e/backlog/-/issues/3670
