After I clicked the Request OTA button, it flashed the running dot for a second then went back to "Request OTA." I am not even sure I actually signed up.
Hi! There should be a message confirming you've requested the OTA, so perhaps you can refresh and try to request it again?
Do keep in mind that beta labs for Nokia 6 is currently not available in US, China and Taiwan due to some additional requirements for technical adaptations. Nokia 6 in US, China and Taiwan will upgrade directly to Android Oreo when ready. This restriction applies to users in US (all TA's), China (TA-1000) and Taiwan (TA-1003).
I see. Mine is US version from Amazon.
I wish I got this information during the verification step. Would save a lot of people a lot of time.
