I have had multiple problems with linphone, including downloading an apparent 32-bit app from f-droid basic.
When I tried to download in another profile, first I got IOError and then I got APK invalid errors about 5 times when downloading it and other apps, then I switched to a different network, still got errors, then I changed VPNs and used circumvention and stopped getting errrors.
This seems to suggest Network 1 is monitored and Network is less monitored (but may have been blocked because of the prior VPN connection.)
Is there any other explanation for this? Network 1 is faster and easier to use than Network 2.
I have also seen other unusual occurances on Network 1 where packets seem to drop for no reason at times, like if I am mo itoring my data I see X Mbps consistently 0-4 seconds, 5 second it drops to 1/100th of X Mbps, then 6-10 seconds it's at value X again.
This could just be a technical probkem with Network 1, except the apks are downloading and installing on Network .
