Lumo by Proton

Sorry to hear that. Could you clarify what exactly you mean by "the user can't answer questions"? Feel free to contact us at https://proton.me/support/contact with more details so we can help. On another note, for more up-to-date information, you can also instruct Lumo to pull information from a web search using the "Web search" option.

Would you mind clarifying your review further? If there's anything we may be able to help you with, or if you have any feedback that you'd like to share with us, feel free to let us know at https://proton.me/support/contact.
