Commenting feature not working and buggy

HI Team,

Please see the screenshots below. It seems that the commenting feature for my Invision Studio prototype is not working. Here is the situation :

1. My co-worker had given total of 6 comments an hour ago but when I checked, only 1 comment are available. The rest is missing and I can't find it.

2. The comments are docking when I scroll up/down and this make the location of the comments not static - hard to pinpoint the location of the comments.

3. I can't reach bottom of my page! Need to zoom out around 70-80% to see the rest of my prototype.

For point (1), this is weird since I think last week the commenting feature works just fine. And it very disrupting my workflow with my co-workers, since we need feedbacking and collaboration as soon as possible.

For point (2) and (3), this has appear since the first time I used Invision Studio prototyping feature. My company use paid account but we found it weird that Invision's own Studio had lesser-quality prototyping feature compared to the Craft plugin (Sketch) based. The feature are way less and it's more buggy, less usable too. We think it should be at least on the same quality. The Craft based one has a much more advanced and detailed feature! Its very annoying too since we essentially paid more for less quality.

Please look into this as soon as possible.

Thank you and best regards

Kevin
