if you see well the day before mid-August on August 14th here in the forum they connected to the PC of a user via teamviewer and they solved the problem.
no company works the week of August (they're all on holiday) spirit instead works.
if you have a problem ask and they solve you if needed they create a software version for you.
look how many topics there are spirit helps all topic authors and they also work on updates and new releases.
ask and give them time to fix, it will be fixed in the next updates.
be grateful because this thing is not due you paid for the control unit but from now you will always have support and you won't pay anything.
From now until they produce it you will have free support I think that's a good thing and it's not nice to ask forcefully.
See what the other brands they tell you that's the control unit make it go well if something doesn't work you won't get help from other brands.
Spirit is different, you try to help people from today until the future, it's not easy.
Anyway I use radiomaster and i have a module elrs and module 4in1 .
For now I use the 4in1 module and I use all 16 channels.
If you use the elrs you know that the elrs receivers do they have various types of resolution?
that is, when you move the stick are moved usec in a different way? 1520/1530/1540/1550 or 1520/1521/1522/1523 ecc ecc
but this is off topic spirit...
Anyway, everything is written here It all depends on how you set it up
