I recently upgraded to R 3.6 version. Here is the problem I am facing:
We are authenticating to Google Analytics and Big Query in the code for the same client account
The code was working well in our local systems as well as shinyserver until we upgraded to R version 3.6..
When the authentication stopped in our local systems, we started explicitly authenticating using service token (bq_auth(path = "R_Dashboard-ecccc1b8eb44.json"). This is working in our local system now but it doesnt work any longer when we are publishing it in shinyapps.io. I raised a concern and the support team said that the problem is with bigrquery package and I have to approach community for support
