logged in today. always do my updates then.
flatpak first--had about 10 packages. by the timeflatpak update got to its 10th package, that's when the Sys Update message popped up (qt package).
So maybe 45 sec passed? Solus was 10 sec (I think) and always beat me to it (sometimes), I may tinker with yours my sweet spot may be 20-25.
PS--it is SO nice to have an alert after removing discover, thank you.
