Hello.
I understand you are a new member and do not know us very well yet
welcome and I hope you will enjoy your time here.

I am using stock FP OS on FP5 - have no issues whatsover with GPS, so I am not usually commenting stuff on other ROMs. But perhaps there is a misunderstanding here - e/OS software is provided by Murena so why Fairphone would be responsible for sorting it out? Plus - to the best of my knowledge - the GPS issues on FP5 are not common, hence the questions about your settings.
Edited to add that there is this thread on GPS issues on some apps, please let me know if that was relevant to your case
