Now is working, thanks

Description:
In Illustrator Beta 2025, proportional scaling does not work as expected. Even when I click and drag a corner handle without holding Shift, the object does not scale proportionally — it stretches freely. This happens with simple shapes like rectangles, using the default Selection Tool (V).

I have:

Reset preferences (Cmd/Ctrl + Option/Alt + Shift)

Checked the "Scale Strokes & Effects" and "Constrain Proportions" settings

Ensured the transform link icon is active in the Transform panel

Tried both new and existing documents

Expected behavior: dragging a corner handle without holding Shift should maintain proportions by default.

Please investigate — this behavior is inconsistent with the expected and advertised default in the latest beta version.

esta herramienta es imprescindible para el trabajo cotidiano de cada diseñador

La herramienta de selección directa no escala uniformemente formas creadas o compuestas, solo escala uniforme las formas regulares creadas con cada herramienta básica de illustrator como cuadros estrellas o círculos, se debe corregir esto ya que es una herramienta imprescindible para nuestro trabajo diario.

When I use the selection arrow + SHIFT, the proportions are not constrained. I tried everything to fix this. However, the shift tool + SHIFT can lock proportions when scaling. I something need to use the selection arrow tool to scale evenly. Please help!!

Using shape shift in combination with image transformation isn't working in the beta version of Illustrator. I tried every possible solution, but none worked.

This issue doesn't occur in the regular version.

When choosing the tools, the function of proportionally scaling the text or images doesn't work. Even if the "shift" key is pressed, the scaling effect cannot be achieved. Now I have to suspect that all your developers are just kids. More and more basic errors keep emerging, which seriously affects the usability of the product.

Version number: beta29.552

Thank you - posted on beta bug forum

Since update to v29.5.0.35, holding the shift key while resizing an object does not constrain the aspect ratio of the object.
This happens whether "Transform Tools" is checked or unchecked.

One exception is if I create a new object using the shape tool. Constraint works for those objects until I alter them, or if I try to resize while another object is selected.

I have reset preferences, restarted Illustrator and the OS.

Illustrator v29.5.0.35
Windows 11 build 26100.3476

Downgraded to 29.4.73 - Shift constrain is working OK in that version.

Proportional scale not working for text, in the new updated Beta version, this is even when holding the shift key.

The text will scale unproportionally based on where you move the arrow.

It would be advisable to report it as a beta version bug.

My work-around was to downgrade to 29.4.73. Shift constrain working OK in that version.
