You've done all the work: you've uploaded media, made it interactive in the Studio and now you notice a small change is needed in the original media file.
No worries, you can replace your media and keep the interactivity just fine.
TL;DR: Upload new media and copy over the interactivity from the old media.
Step 1: Upload your new media
Don't delete your old media just yet! You first need to upload the newest version of your media just like normal.
Step 2: Go to the old media and move the tags
Go into the Studio of the old media.
Click the media options and select "Copy tags".
Step 3: Select your new media
Now a modal will show up asking you where to copy the tags to.
Just select the new media, or click the 3 dots for the overwrite options.
Select the new media and that's it! Your tags will now be copied to your new media. After checking that the copy has been done successfully you can remove your old media.
