I strongly recommend to use the playstore instead of Aurora. Aurora is mainly made for users without gapps. If you have gapps installed (which is the case with stock fairphone OS), you should install google apps, from googles playstore to make sure it’s installed the way the app expect it to be.
I changed my APN with the specifications on the post:

MMSC: http://mms.orange.fr/
MMS proxy: 192.168.10.200
MMS port: 8080
MCC: 208
MNC: 01
Authentication type: PAP or CHAP
APN type: default,supl,mms,hipri,fota,cbs,xcap [note: this is probably a bit many, but I put them all - anyone recommends differently?]
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4

MVNO type: None
MVNO value: Not set
I had cases where apps won’t work (properly), e.g. Android Auto-apps 100% don’t work at all in the headunit if not installed from the playstore (or with the root-installer of Aurora). Auroras root-installer flags apps as installed from playstore. Non-root will not do it and that’s what can caue issues.
