Just fyi: Admin answered to this issue regarding an suggested fix:
Thanks for the suggested fix, it will be included in the next update so we can see how it works. I'm still working on some modernization updates for the app so I don't know when the next version will be published quite yet.
I believe the root issue is that the current deployed app is on an old version of electron and cloudflare sees that as suspcious. The next update will also include a newer version of electron which should also hopefully prevent the browser checks but we'll have to do some more testingt.
So the issue is known and hopefully fixed in the future. Thank you @leafo
