Version info (optional, but sometimes helpful)

• Android version: 12
• App version 2024-03-29-2245-fd304c53-fdroid

Additional context
Note that fifteen (along with hex and twiddle) doesn't provide much help on how to solve the puzzle by using the "show solution" button making this issue especially noteworthy
