Hi, in my network I have an ad-blocker https://pi-hole.net/ and couldn’t login into the app. One of the URLs that’s redirecting through the universal link when logging in was probably resolving through some ad network and therefore gets blocked.
Solution was to either use 4G (don’t go through local network) or pausing ad-blocker when logging into the app. After login the app works fine.
Didn’t dig too much for the DNS record that gets blocked but maybe freetrade devs could have a look and maybe use some alternative method to track logins or maybe login link is added to one of the ad-blocker lists by mistake, you could possibly open a PR to remove it.
