I've had a free email account since 2016, and started to really use it in 2020. I did not managed to use proton bridge with Thunderbird at all at the time, but the webUI was good enough. I recently started to use calendar and now pay for the service. Basically: once a new feature/product exists, you will have to wait before it's really usable (Pass might be the exception). I wouldn't use their cloud storage yet, if it's a deal-breaker, wait a few months, maybe a year. Really happy with the support, the few UI/UX changes, the performance improvements over the last 4years.
