Hi,

"The extension works fine with version 157 after adjusting the strict_max_version parameter in manifest.json."


I modified this setting in the manifest.json file.

I re-compressed the archive and saved it in XPI format.

When I start the installation in Thunderbird, I get an error message: "Provider for Google Calendar could not be installed because it is not compatible with Thunderbird 157.0.1."

What should I do, please?
Many thanks,
Richard
