I keep having some oddness with the iPad version of Logos, on a M4 13" iPad Pro (8Gb RAM). I have two different but very similar layouts, one for greek reading and one for Hebrew. Each one has several tabs: 4 translations in one, BHS/UBS and UBS Translation handbook in another, HALOT/BDAG in another, 4 study Bibles in another, and a grammar.
Often as I reload these or swipe between them, one of the panels will be entirely blank. You can't even tell what book it is unless you tap in the ToC. Often this is the grammar or the lexicon, but recently I've started seeing another variation of this, per screenshot. Here I had to force-quit the app.
