Date for Chiffre d’Affaires

I am an English teacher online and I have recently started teaching for a new online platform.  I am registered as an auto-entrepreneur, and in terms of the pay:

-The students pay the platform for classes beforehand, and then get credits for classes that they can use with any teacher (upon the teacher accepting their request).  After I teach each class, the agency releases the monetary value for the class into my ‘wallet’ on the platform.  There is a record of when the funds for each lesson go into my wallet on the platform, but I don’t yet have access to, or control of, the money.
-I can then withdraw the funds from the wallet on the online platform into my Payoneer account, and I can choose when I click the button to ‘withdraw’.  But I have to then wait for a set ‘payment period’ for the platform to actually transfer it to my Payoneer account (so that I can access/control it), and the platform controls when they pay the funds into my Payoneer account, within that period.  E.g. if I request a withdrawal between the 1st-15th of the month, the platform will transfer the money into my Payoneer account at a time of their discretion, between the 16th-26th of the month.  Once the amount goes into my Payoneer account, I have control over the money and can choose when I transfer it from my Payoneer account into my bank account.

For my Chiffre d’Affaires (and to use accurate currency conversation rates), I’m just wondering what date I should declare that I received the payment on.  My options:
a) Declare the payment as received on the date that it is received into my wallet on the platform (but I don’t have control over the amount on that date)
b) Declare the payment as received on the date that it is received into my Payoneer account (then I can control and have access to it)
c) Declare the payment as received on the date that it is received into my French bank account (after I have transferred it from Payoneer to my bank account).

Which date do you think I should use?  I think it should be option (c) – declare the payment on the date that it is received into my bank account, but…

I also teach for a different online platform, and with the other one, I declare the payment on the date that it is received into my wallet on the platform.  But the difference is, with that platform, I have control over the money as soon as it comes into my wallet because I can choose when to transfer the money (into my bank account via Transferwise), and the transfer is automatic.

Would it be ok to use these different date systems for these different platforms?  So:
For the new platform: declare the payment on the date that it is received into my bank account
For the other platform: keep declaring the payment on the date that it is received into my wallet on the platform

They are slightly different situations in terms of when I have control over and access to the money, so I think it would be fine.  But I just don’t want to be punished for my method not being consistent between the two platforms…
