MMS reception issue on FP3/FP3+ (In France)

Yes I did tried QKSMS and the issue is coming from this app…
The app message which is working is the google one. And fun fact, when I installed it I get access to all the MMS I did not received before. Therefore, the mms are somewhere and I don’t understand why it is not possible to get the on QKSMS or e app. (But the great thing is that your MMS are not lost… If you are ready to use google message).

And I have to add one thing : when I went back to /e/ message app after that, it has downloaded some MMS sometimes, but not all of them…

I do not understand a thing…
