=== THE BUG ===
Reconfigure does not work in Arena as intended with auras that transform into creature.

What should happen: If a permanent with reconfigure is attached to a creature (so the permanent with Reconfigure is currently not a creature) and then an aura is attached to it and makes it a creature, the permanent should unattach and become a creature.

What happens in Arena: The permanent with reconfigure is still attached and doesn't become a creature.

=== PROOF OF THE BUG ===

I'm including two pictures showing the bug: before and after attaching Ensoul Artifact to The Reality Chip. After attaching Ensoul Artifact to a The Reality Chip, The Reality Chip is still not a creature, when it should.

This is not an isolated bug, it is easy to reproduce with any card with Reconfigure and auras like Zoetic Glyph or Tezzeret's Touch.

In Arena the permanent correctly becomes a creature with the effect of cards like Synthesizer Labship, The Blackstaff of Waterdeep or Bring to Life just to name a few, but for some reason it doesn't work when the effect comes from an aura.

=== RANTING ABOUT YOU NOT FIXING THE BUG FOR SO LONG ===
This bug isn't new, it's existed since Reconfigure was introduced to Arena, and for some reason, it still hasn't been fixed.

I have reported this bug before, FOUR YEARS AGO, it was archived without being fixed, why?: https://feedback.wizards.com/suggestions/45556654-bug-with-reconfigure-and-ensoul-artifact

I have also reported this bug through other channels.

This bug affects the deck I play most often, there have been multiple occasions where the malfunction of this interaction has been the direct cause of me losing the game. There have been multiple occasions where I needed to transform The Reality Chip into a 5/5 to attack and win, but by not being able to do so I lost when the opponent attacked on their next turn.
