1920x1080 artboards are shrinked in shared prototype viewed on 1920x1080 resolution monitors
1920x1080 artboards are shrinked in shared prototype links when viewed on 1920x1080 resolution monitors or lower.
It is impossible to make an accurate usertest, when everything differs from the designed artboard size. :(
Made in 1920x1080 = Review in 1920x1080, not shrunken down.
Thanks for your report. Can you provide us few more details?
1. Are you seeing the problem in particular browser?
2. Does it happen for all prototypes or a specific file?
3. In which OS, reported problem observed?
Would it be possible for you to share prototype link, movie file (.gif/ .mov / any format) showing shrinking issue?
