I’ve thinking about purchasing Proton Mail Plus only and just only to have IMAP support, but I’ve looked all the features that the Proton Unlimited Plan have, and honestly I believe it’s worth, but I hate having all the eggs in the same basket.
The features I believe worth the most are the 500GB storage, IMAP support, all the VPN servers with P2P and unlimited SimpleLogin aliases, but when I ask if it is worth the price I mean, the majority of those features I can have them having individually with others services and even at lower price.
I have it, I use proton Drive for mainly photo backup from my phone. Mail for my email, and the VPN service.
Totally worth it for me, all their apps run well on my phone and their web interface for email is great.
Does the background upload works for you?
So far yeah. There was a bug a few months ago that prevented the background backup function from working reliably, but it’s fixed now.
