Hello, past sync for Reddit user here. I heard connect was a good app to use as it had similar look and feel here on Lemmy. I was using for a day or two when I spotted this in my duckduckgo app tracking protection screen. I can't say I have come across an app using so many different trackers, any reason I am not aware of for all these? Thanks
'Connect for Lemmy' doesn't seem to include ANY trackers, see this analysis: https://reports.exodus-privacy.eu.org/en/reports/com.kuroneko.lemmy_connect/latest/
The blocked activities are probably links you accessed in the integrated browser of this app.
