Bug fixes - After switching to a new device or restoring from a backup, Bluesky notifications could stop arriving until you turned them on again in Settings. The app now checks your notification registration every time it starts. - After logging out, notifications for the logged-out account could keep arriving on this device. Logging out now stops notifications on this device. When you log in again, turn notifications back on in Settings. - The app version shown on the Settings and Login screens was out of date. It now shows the correct version. - The app could say an update was available even when you were already on the latest version. - When your login had expired, the timeline and other feeds could keep loading without finishing. - A reply or quote could be attached to the post you had selected before, instead of the current one. - Scrolling to the bottom of the timeline could load the same next page twice. - Some colors on the thread screen did not change when switching between light and dark mode. Improvements - When a word's translation cannot be shown, the message now explains why: the offline dictionary is not downloaded, the word is not in the dictionary, or the text is a sentence, which the dictionary does not cover.
