There are a few people I know who are having problems accessing Stumbler, getting server app issues (403 error).
Is Stumbler offline? Will it be coming back online and when, please? I noticed Stumbler has restricted its home page and that the app has been removed from the Apple App Store? Are there problems with the Stumbler company?
I located a thread here from 02/2021 regarding the retirement of Stumbler [from the Android store] due to the developers not keeping up with updating the code (therefore new content would not play, etc.), but that was a long time ago, and Stumbler continued to operate for nearly two more years after that. (Retiring Mozilla Stumbler)
I know this is a forum for developers, but there are no available forums that I can find for end users on this topic.
Thanks for whatever info you can provide.
