Hi, thank you for maintaining your tool, it's immensely useful. Wanted to write a quick email to note that apparently MEGA's new "security upgrade" seems to have broken megatools. From what I've gathered, it seems to be related to this:
https://blog.mega.io/e2ee-security-update/

If one logs in to one's MEGA account on browser, it will prompt asking to "upgrade the security of the account" and that it will be a one time thing.

I've accepted the security upgrade on one of my accounts and megatools will no longer work properly. For example, it won't list folders (it seems to still list files on Root). This is the terminal output when trying to ls:

> WARNING: Skipping import of a key 8K5C1XXX because it's authentication failed
> WARNING: Skipping import of a key dLxAgXXX because it's authentication failed
> WARNING: Skipping FS node dLxAgXXX because node key wasn't found
> WARNING: Skipping FS node 8K5C1XXX because node key wasn't found
> WARNING: Skipping FS node BWo21XXX because node key wasn't foundWARNING: Skipping FS node oLwSwXXX because node key wasn't found
> ...
> /Contacts
> /Inbox
> /Root
> /Trash

I have 2 root folders so I imagine the first 2 warnings is about those folders and the rest about sub-folders.

When doing ls again, it will skip all the warnings. Only when deleting the "megatools.cache" obtained from the first login will the warnings appear again. I assume this is normal behavior.
Since I don't have any root files and my files are in folders, when I stumbled upon this, megatools gave me the impression that my storage was empty when it wasn't, so that was a bit of a shock.

In any case, it's clear MEGA has changed things on their end, it would be very much appreciated if you could look into it and possibly find a fix. Thank you once again.
