Apos fazer o processo de instalação do dropbox ele faz o sync porem nao aparece o icone nem mesmo da para saber se está sincronizando ou não.

To be honest, the dropbox plugin has not had any work recently as we are working of a new cloud provider interface which will supercede it. I'll see if I can get the plugin working in Juno.

I get the same:

$ io.elementary.files

I just tried compiling and installing the dropbox plugin from source and Files runs OK. The dropbox emblems and context menu also work.

It looks like there is a binary incompatability between the version of libpantheon-files-core that was used to compile the deb and the one used for the current Files package,

I have pushed a PR with more detailed instructions for installing the plugin from source.

This should be working now after update and reboot.
