Mobile app and Desktop do not sync

I installed meta mask on my desktop. I subsequently downloaded the mobile app for IOS and synced both.
After that I Installed a custom network on the mobile app and added custom tokens on the app version. Also I added a different custom network on the desktop version.
When I open the desktop version I have no acces to the custom network I added to the mobile version.
When I open the mobile version I have no acces to the custom network I added to the desktop version.
I have tried recovering both versions with the secret seed to no avail. Desktop version remains as it was and so does the mobile version.
I have also tried to import the accounts on desktop to mobile and the accounts on mobile to desktop only to show an error.
