Well... I live in Poland, there is no Apple Store. and I havee 2018 MB pro touch bar 13". I have an issue with the keybooard for 3-4 months now.
I went to authorized Apple reseller. They took my macboook for 3 days and they after that they just told me "all good".
I have problems with all line from Q to P letters. They can work foor 20-30 click and than from time to time I got double, for example: "oo".
yep... according too them it's fine

I have recorded the issue with my phone camera and I really hope to have it fix once for good.. one day
I really miss my 13" pro mid 2014..
