Adding color in Adobe Animate

[minox27757567xyod]

Just started using Adobe Animate (or generally started learning animation) 3 days ago and hitting a roadblock which I can't figure out. From my research, Brush tool (Paint inside mode) and paint bucket tool (I have tried using different mode such as Closing big gap) is used to add colors to the area.

But then, Im having issued to add color in a larger area (as shown in the image - red arrow). Using brush tool (Paint inside mode works but is a pain in the ass which it wont just paint inside the area I want).

Anyone can provide me a solution with this? Really needed the help. Any reply will be much appreciated.

is that a closed shape?

Yes, I believed this could be the issue. But then I faced another problem which is when I zoom in, I can add the color, but when I zoom out, it doesnt work suddenly. Video reference: https://cloudmails-my.sharepoint.com/:v:/g/personal/tp053611_mail_apu_edu_my/EXKiTwDPA7hMqemYNp1mt9Y...

And also, thank you for taking time to reply.

i can't duplicate that (apply a fill at 99% zoom, then zoom to 123%).

what happens if you repeat those steps and then zoom to 100%?
