THIRTYNINE themes??? You beat me hands down :-)
Themes contain many (graphic) files, and the access method under Android 11 makes that slow in comparison to earlier Android versions. I am not an Android DEV, so I cannot go deeper, sorry.
BTW: as Locus makes an internal (!) uncompressed copy from the ZIP files (but I do not know WHEN that happens): is another start of Locus slow again, or better then?
