Simplify stuff , stop keeping things so convoluted, see your recent playstore reviews.
If this app is an Enterprise app then its okay may be, but mostly enterprises don't need such apps as they already have tons of software to mange their workflow mostly coming from Microsoft & others like Jira etc.
For personal users, this app is too confusing & there is a learning curve, which I don't want to travel for sure.
No monthly view calendar for personal premium plan, doesn't justify things. Any.do is depending on 3rd party integrations more than creating its own features.
You have some advantages like whatsapp integration and better reminders, but you lack the simplicity of UI like Microsoft To dos. That app has a nice simple UI but lacks tons of features and is unreliable at times in reminders.
