Takes to much free space.
I know it is 2.0 and is outdated, but is there any way to delete that 1.3 gb of data without removing the entire bluecord? I using it just for notifications, i don't want to reset data because it may break. Maybe i can delete that 1.3 gb of data using adb or what? So annoying that this takes that much space.
Why would anything break? Assuming you mean you want to preserve your Bluecord settings...
The best I've got to easily do this is to screenshot your Bluecord settings, clear app data, then use those screenshots to reapply your previous settings, to configure the app how it was before.
If your phone is not rooted, you cannot retain your account switcher backups. If you're rooted, my suggestion is to use FX File Explorer, visit the app directory, and find the file that holds the accounts, back it up, then copy the file back in, or manually restore each account token by logging in with them and adding them back to the account switcher backups.
If you'd like to proceed with clearing the data, I suggest go all out and just uninstall Bluecord and install the latest version fresh. Makes life easier.
Just remember this is not the place for support.
