Well, if it’s truly end-to-end encrypted, then your client device needs to do the encryption/decryption with its own CPU. It seems the application checks for minimum specs for that requirement and they are either too low, or your specs can’t be determined.

IMO that’s kind of a dumb requirement because it would still work, it would just perform really slowly.

your photos are encrypted on your device for obvious privacy reasons. that text says that your phone is not powerful enough to encrypt them.

I thought we had a "no support question" in the rules, but seems like not. I'm probably going to add one tomorrow, except if people comment here that they prefer not to.

Try setting it to desktop site in your browser and see if it gives you the same shit. It could be legit, but a lot of web apps like to pull shit like this to force mobile users onto their mobile app
