Release date: January 25th, 2019
The update 5.0.4 mainly fixes many crashes and bugs.
This includes a fix for a problem with the contextual area of the Image Tool. Now everyone should be able to see and drag & drop their recent photos from the contextual area to the page.
About lag when writing, scrolling or erasing:
Some people, especially on older devices, experienced a lot of lagging when writing, scrolling, or erasing. We've worked hard on optimizing the performance of GoodNotes in the last two days and are preparing the update 5.0.5 for release early next week. This update should drastically reduce the lag so that you can write, scroll, and erase fluently again. Thanks for your patience.
