i love proton mail and calender so much for my business. i use it because i do not trust american companies and this is the best alternative, maybe even better. but the fact that i cannot sync my proton with any 3th party services for my business software erp. like i cannot sync my calender and such forces me to still create a google business account instead of proton. so it would be amazing if u could like find a way to make 3th party integrations alot easier.
