In order to reproduce this bug, using the branch in https://github.com/sympy/sympy/pull/20612 I have the following: ```python In [1]: from sympy.utilities.matchpy_connector import WildDot, WildPlus, WildStar In [2]: from matchpy import substitute...

> As a first step to investigate this, you could remove the `sorted` and run the tests. Here it is: https://github.com/HPAC/matchpy/pull/66 > I have the following idea to solve this...

> I don't think that removing or changing `sorted()` in `substitute()` is sufficient. I remember now that we sort operands in commutative functions to ensure that expressions that are equivalent...

> Does SymPy automatically sort operands in commutative functions? `Add` and `Mul` have their own constructors that do indeed end up sorting the expressions. The transformations undergone in the constructors...

> I guess it would also make sense to add tests for the SymPy compatibility before the next release. Are you working on those tests? We have [these tests](https://github.com/sympy/sympy/blob/b20927c89cb4b74c49cae50ea6425f6d7a6826dd/sympy/utilities/tests/test_matchpy_connector.py) in...

Didn't realize MapBox is close-sourcing its API. That's bad news. Maybe it's better to see if there is a way to open the track in OsmAnd?

What about using osmdroid for the F-Droid version?
