I am having an issue when ads reload, especially the ones that appear above and below the first posting. When either reloads, the space it occupies shrinks for a split second as if nothing is there (in effect going from 250px to 0px). This causes everything under it to jump up and down during the reload interval. It is distracting when reading or trying to post. This occurs on MacOS/iPadOS using Safari. It is not an issue when using Chrome (or not that I have noticed).
Not sure setting that space to a fixed height would resolve the matter or not. If needed, I can try to create a gif that shows what is happening.
