The main cloud services don't even work natively (GoogleDrive, OneDrive, iCloud) basically the only mainstream choice is Dropbox. I tried to use Google Drive in Mint, and it's a pain to get it to work, and usually it stops working after computer restarts.
Someone has a recommendation about how to handle these services?
You don't need insync - most people just automate rclone sync commands using whatever task scheduler their system runs by default (cronjobs or systemd units, typically). For those who prefer a GUI, KDE has a Scheduled Tasks app.
On Android, you can use Round Sync which is a wrapper around rclone and can import the same configs.
