I totally agree. I had the same problem with the slow connection speeds after installing the Google bing replacement. I had so many problems with it locking up that I ran it without the bat file and cmd window and my system would still lock up.
I eventually had to totally remove MSFS2020 from my computer and do a reinstall. Didn’t get all of the folders deleted, so I had to do a second re-install. Finally after 4 days, I had MSFS 2020 working where I could actually be in the cockpit of the plane, but I was then suffering from the connection issues.
After reading your post, I went to the FAQ of the mod on flightsim.to and followed the following:
App should restore to bing map when it close, if not, please delete The following two lines in the C:\Windows\System32\drivers\etc\hosts file:
127.0.0.1 kh.ssl.ak.tiles.virtualearth.net
127.0.0.1 khstorelive.azureedge.net
Rebooted my machine, logged into MSFS 2020, and no issues with connections to the server, or being switched to offline mode for streaming dynamic data from bing maps.
I wanted to try the Google earth mod, but in the end, I fought it for 4 days and had to do a complete nuke and pave of the MSFS 2020 program. Now all the hobbs meters are set back to 0. I use Little Nav Map to log my flights. I need to figure out how to export the log to excel, total up the hours for each of the planes, and then edit the appropriate files in MSFS 2020 to update the hobs meters.
I think about how hard it is for MS and Asobo to trouble shoot these kinds of errors. The Google earth mod, even with a complete re-install of MSFS 2020 was still messing it up. Asobo and MS would say to clear everything out of the community folder. Mine was completely empty yet I was still having issues playing the game. Finally after clearing out the host file, nothing related to the install of MSFS 2020, the game finally works.
