I kept getting a notification to confirm my tax residency, but every time I reached the “Read and Confirm Declaration” screen, I couldn’t actually select the “Confirm Declaration” button.
It took me longer than I’m willing to admit to to figure out what was going on, but basically it’s this: On my Pixel 2XL, my font size was just small enough that the declaration text fitted on screen without scrolling. Once I adjusted my text size so that it was large enough that I could scroll the declaration text, it allowed me to confirm my tax residency.
So, my suggestion would be this: If the declaration text that we need to confirm fits fully on screen without needing to scroll, please just enable the “Confirm Declaration” button.
