    Just found this same bug (2019.4.22) looks like it is fixed in the 2019.4.23 release notes:

    iOS: Fixed a regression that meant devices with memory over 2GB reported negative amounts of memory. (1319420)

    Why is this marked as duplicated with no link to the "original" report? I cannot find it anywhere and every other similar issue is marked as fixed when I'm still experiencing it on version 2019.4.20f1

    This is a major issue. Will it be resolved soon?
