I would not be so vigorous in endorsing any subreddit, especially not one that is related to financial matters. I will attempt to frame my salvo, with the express intent to inform. No money was lost.
After trying to subscribe to Freetrade and Trading212 (Robinhood equivalents). I was unable to register with the former ─ a bug they mention regarding deep links in their FAQ, referencing an older version of iOS. I followed their instructions on troubleshooting, without any success ─ found an arcane way to get to the chat session (really hard, without being subscribed to the service), which resulted in no action. However, it was really surprising to find out that asking for help in this subreddit, where this app is held in high regard, elicited no response and only downvotes. Always assume some inherent bias, where money is concerned; don't follow blindly and stumble across problems, after the event.
Also the discussion is two way, so you get to ask questions without paying hundreds to an IFA. In some instances you probably should speak to an IFA (or an accountant) for a holistic overview of your particular situation, but redditers are quite quick to point that out too.
For anyone based in the UK, please go and read the content at https://ukpersonal.finance/, it is invaluable for your future. Financial literacy for the millennial generation is my #1 recommendation for general life improvement. It doesn't matter what situation you are in: in debt; with lots of savings; lack of credit options; etc... You will learn tremendously and can genuinely improve so many aspects of your life.
