Snapchat friend suggestion - does this imply a GDPR breach?

[bubblebees]

I recently joined a national professional organisation. It took some time to receive my membership pack and I had to chase them up more than once, so my confidence in their processes was a little shaky right from the start. I had some email correspondence from a <Joe.Bloggs>@<organisation>.co.uk who also called me on my mobile to discuss my query.

So I've just fired up Snapchat to check my DCs activity through the family monitoring service. This is literally the only use I have for Snapchat. My DC is my only "friend" and all privacy settings are tightly locked down. I 100% have not allowed Snapchat to see my Contacts.

But my top friend suggestion is now "Joe Bloggs". I can only assume that he uses Snapchat on the same phone he uses for professional calls and has shared his Contacts (including my phone number) with Snapchat, allowing it to draw a connection between us.

Is this a GDPR breach, and if so how should I approach it? Regardless, I'm really disappointed and my confidence in this organisation - whose sole function is to provide support to members experiencing professional difficulties - is now really low. Advice appreciated.

Edited to remove a post I realised was useless!

Snapchat has a lot of ways of suggesting friends, including random suggestions. I wouldn't jump to the conclusion that he has added you to his contacts and that is how Snapchat has made the connection. Even if he has added you to his contacts and allowed Snapchat access, it is more likely to suggest you as a connection to him rather than the other way around. Without something more solid, I doubt you will get anywhere pursuing this as a GDPR breach.

Maybe your phone heard you speak about him. I swear my phone hears me and responds, for example with ads for things I have just mentioned with a friend in conversation, etc
