Am I missing the point of the text syncing?

After watching it crash my phone, for daring to try save the nextcloud credentials into dashlane. I choose not to use the dashlane app, and watched the population of my SMS’s in nextcloud.
Losing all the contact details apart from numbers, and not actually allowing me to send an SMS from the webpage, had me wondering… whats the point?

I don’t understand why the android app in the playstore isn’t free (considering the quality, and lack of functions). But I got a refund pretty quick, and went back to using pushbullet.

Comparatively, It’s got more features, and free. One less thing to add to nextcloud.

Maybe it worth exploring the api’s for pushbullet instead of reinventing the wheel?
