LibreLink and Samsung Galaxy S20?

It's not listed on the Abbott website (https://freestylediabetes.co.uk/landing/smartphone-compatibility-guide#compatibility-list).
However, nor is the Pixel phone I use nor the Honor phone I used before that.

In my experience, the version of Android has been the deciding factor. However, I have always avoided Samsung phones as their Bluetooth implementation does not have a good reputation. Yet, you have been using the S8 with no problems.

Sorry, I started this message with the intention of being helpful and I now realise I used a lot of words to say "I don't know". Forgive me for waffling.

I have a Samsung galaxy S20 FE and it works fine. I had the same problem, had an S6 but had to upgrade to use the libre as the S6 was not compatible. I've had no problems and it works fine.

I have a friend with the same phone as me and uses the librelink with no issues.
