iPhone 17 Pro, iOS 26.2. When looking at a post if I sleep my phone and unlock it, the Voyager window will look shrunken, not filling the screen. The top bar remains the same. Force quitting and reopening resolves the issue.
Same thing happens to me, but only after my phone rotates from portrait to landscape and back. Doesn’t happen all the time; maybe 50-60% of rotations. Force closing the app and reopening fixes it for me.
