To focus in your core product, mail.
Handle attachments can be good with drive tools, edition of the files, etc...
And stop the continous bait towards Proton, I changed my mail from proton to tuta, for the ia, crypto wallet stuff, and some vague political actions they had. Stand out if they do anything wrong, but in the meantime there has been too many post that goes against them without any purpose, and it is starting to be detrimental to your image.
keep the good job:)
