Couldn't forward emails until about a month ago.

Their drive app backs up only the computer it's on and other computers cant access that backup. It's like a sectioned off part. Or I can upload files that any of my devices can access.

Their calendar has some problems with compatibility of run into and it's things that the person on either side can't change. Not world ending but it's really annoying.

They literally just added the ability to automatically add holidays to the calendar. And of course I had set it up about a month prior so I manually entered everything.

The proton drive app for your phone doesn't automatically back up anything.

I'm not shitting on proton because I'm an active proton unlimited subscriber and I use a bunch of their services, but I also recognize the flaws and how it's not as seamless as Google yet, which I don't expect it to be.

I also wish they had some better Linux support in preaching to the choir with that.

Love their vpn and the netshield features. Email works great and I love knowing I can read an email and automatically have trackers blocked. Aliases are great but I use their simple login site free with my proton subscription too. So my point is I like them lots, but it's not a complete Google replacement yet.

In addition protonmail do not protect your metadata (from memory), it's not encrypted in transit.

Protonmail also keep your public and private keys on their servers, it's PGP however they don't want the end users to have to manage their own keys. That to me isn't ideal.

Receiving from another provider you'll get TLS encryption until it hits protonmail servers but protonmail will then decrypt your email and again encrypt your email using your PGP stored on their servers.

Sending an email from proton to another provider will be encrypted on protonmail servers but that's where it ends. TLS will take care of the in-transit and again may not be stored securely on the receiving end.

He wrote their instead of they're, make your judgement.

Tuta (in my eyes) is a step in the right direction, using a client like thunderbird or enigmail and managing PGP yourself would be more secure as the message is decrypted by the recipient and not a company owned server.
