thanks for the ID. It seems that the app now cannot read your data from the database as I expected. For some reason, the error is now "SQLiteReadOnlyDatabaseException · attempt to write a read-only database" even when app just tries to open the database for "Read only", weird.
My suggestion: do a manual backup of the Locus/data/database directory. Then delete this directory. Start Locus Map and it should create a new directory with empty databases. When all will work, close the app, delete new empty databases (directory "database") and copy back old data.

thanks. And you copied the equation into the waypoint description. The difference is that I've copied it just into the clipboard.
Hmm, this helped me a lot with the last caches, but understand that it may also contain some old "clipboard" data. Oki, I may hide it for now. I'll try later to detect if the clipboard contains an equation and display it only in this case.
