The Tracify data for the Dashboards as well as the Plugin are retrieved from the same data source. For this reason, getting different numbers here is quite not possible.
In the vast majority of cases, there are different settings applied in either the Plugin or the respective Dashboard which consequently leads to a different data output.
The following settings affect the numbers you are seeing
In the screenshots below, you see the numbers in "()" indicating the settings described in the bullet points
Selected time frame in the date picker (1) of the Ads Manager or the Dashboard
Attribution settings (Attribution window (2), Report time (3), Attribution model (4))
Selected touchpoints (Meta, Google, TikTok, etc.) (5) → Plugin: Multi-Channel tab
☝️ If in the Dashboard no Multi-Channel Selector is available all touchpoints except "Organic" are selected
Selected time zone → Settings tab in the Plugin and the Dashboard
Lastly make sure that in the dashboard you have all your stores selected, that the ad account you are viewing is sending traffic to

👉 Make sure that all these settings are identical in both the Plugin and the Dashboard.
What if my numbers still differ after I have diligently double-checked the above settings
In some cases, it can be that it has to do with your Chrome Browsers' local cache that's interfering with the numbers. This is affecting only the numbers of the Chrome Plugin. Metrics in the Dashboard are not affected by this, so these are in such an exception the reliable numbers.
Steps you need to take in such a scenario
Close your Chrome browser completely and restart it
Go into the respective ad account via the Business Center / Business Manager (not a bookmark / direct link)
If finally this didn't help, please follow the instructions to clear your Chrome browser's cache here.
