I wish I could recommend this add-on as the ability to pull data from Google Ads straight into a Google Spreadsheet is incredibly useful, but there's one major issue with this add-on: report scheduling.
Reports always update sometime between 3am and 4am Pacific Standard Time - a great time to update if you're in that time zone. Where I live and work, that's between 11am and 12pm - a terrible time to update as I need to have the figures ready when I go into work first thing in the morning. Sadly, the scheduling options in this add-on do not allow you to change the time the report updates.
While there are other issues that I can work around - the Choose Columns drop-down menu doesn't scroll properly so I have to highlight the text and drag the mouse down to scroll - the inability to change the time of day the scheduled reports update is such a huge one that I cannot recommend this add-on in its current state. If the developers fix this problem, I will happily amend this review and award a higher rating.
EDIT: Since the end of July 2020 the add-on has not allowed me to create new reports. It just gets stuck loading forever when I try to get the list of accounts. The reports I have already created continue to update as usual but the inability to create new ones makes this add-on effectively useless. The issue I described in my review prior to this edit was never resolved.
