I've been trying to follow the tutorial with a melting text.

I’m quite a new user of Blender and I’m really struggling with an issue at 12:02 of the video.
After hitting ‘Bake All’ my fluid domain still remains as a solid shape instead of disappearing like in the video.
I’ve tried to recreate the whole file from scratch but the problem is there.
I’ve attached some screenshots of my scene and settings.
Are you able to help please?
I have no idea what I've done wrong.
Thanks so much for your help in advance.

Hi Aleksandra AAleks T ,
I can't see anything wrong with your Settings from your screenshots...
Could you upload your .blend file (to dropbox, Googledrive, or any filesharing service you like) and post a link here?
Thanks for a very quick reply! I tried the viscosity and no change. Here is the link to the .blend file: https://we.tl/t-j8q36k1ZU9 Thanks!
Hi, thanks for the file Aleksandra,
It's a classical problem, you didn't Apply the Scale of your Domain.
Free the Bake, CTRL+A > Apply > Scale, Bake again.
For good measures, I'd Apply the Scale of the Text Object as well, although I don't think that makes much difference here.
Omg that's perfect! Thank you so much, this helped with the issue. Do I need to apply the scale to all the elements (domain, floor, text) every time I build a scene? What does it do?
It is good practice to (almost) always Apply the Scale (the only exceptions I can think of, is when you are using a Texture with Object Coordinates, then you need to be aware of what you are doing...,or if you have linked Objects that you want to have different sizes (Scale))
In this case, the Domain is the only one that is really important. When Baking, the Domain takes the shape of the Text Mesh, but because the Domain was Scaled, that fluid is being scaled up by the same amount, making it so huge that it filled the whole Cube that has become the Domain borders, so it looks like nothing happened....
Each Object has its own Coordinate System and Scaling something in Object Mode, scales that Coordinate System. Scaling in Edit Mode, changes the position (coordinates) of the Vertices in that Coordinate System. Applying the Scale, after having Scaled in Object Mode, has the same effect as Scaling in Edit Mode; the Object's Coordinate System is being reset and the Vertices' coordinates are being changed, so that the Mesh looks the same after Applying the Scale, as before Applying the Scale.
It's not easy to explain this in text, but I hope you get a 'feeling' for what is happening. No need to understand it completely (yet).
Thank you so much for your advice and all the explanation! That was extremely helpful.
Oh no, I have another issue with the melting animation now.
When I keyframed viscosity the domain doesn't disappear.
I applied the scale and baked all, I don't have any other ideas what to do.
The action is being explained at 14:51 of same tutorial:

Maybe you have an idea what's wrong?
Screens attached and file https://we.tl/t-U00icTlfu8 here.
My last question (hopefully) is about rendering.
After going to Render/Render Animation, the pngs that I'm getting show the liquid on the solid 3D text layer.
I'm not sure why is it visible there, since I can't see it in my project scene.
Are you able to help again?
Is there any good settings/tips for rendering in general that you could share?
Thank you so much!
