App Store: Recently applied updates show up inconsistently
Since updating to Mojave, the "Updates" is showing applied updates inconsistently. Sometimes it shows apps, that were updated a couple of days ago (e.g. iA Writer showed up there the last two weeks) and other times updates just vanish after they are applied, making me unable to see which apps were updated and what the version notes are (e.g. Bear was updated this morning, but I only found out by accident). Especially with automatic updates it is a pain, not to see all past updates.
How can this be fixed?
(I assume it is a bug and Apple has to fix it, but I am grateful for any low effort, intermediate ideas how to lessen the problem).
