Been a DIGITS user since the Beta. My Google contacts on the web client have to be re-imported every day, even when I'm still in the same session.
It's a pain enough having to constantly re-login and re-register my line all the time, but having to re-import my contacts as well? It's enough of a pain that sometimes I won't even do it, and I just start memorizing people's phone numbers.
This was somewhat understandable during the beta in 2016 but it's April 2018 now and the web client is still just poorly developed.
At least please save my contacts so I don't have to re-import them every day.
