As a temporary workaround for the Google Play issue, you can install the new upcoming Google Play update from this link: https://cdn.organicmaps.app/apk/OrganicMaps-24081605-GoogleP...
Just to clarify, is this Google Play update "upcoming" in that it is currently going through Google's policy review process in order to reinstate your app on Google Play? If so, what changes were made in this release to satisfy their policies?
I'm interested to see what technical hoops you're jumping through to get your app reinstated, if you don't mind sharing. As a developer myself I've had my "fun" with policy compliance and review processes. All the best either way, hope it gets reinstated soon!
My approach was more as a p2p system of mutual random packet bouncing rather than using ICMP ping.
Edit to add: I simulated a network of peers and rendered some videos of a single message propagating through the network: https://github.com/AlexanderParker/clacks-tests/blob/main/pr...
Recovering your file in this way would take some time... "Eventually" you'll get it back...
