#Signal again is having the issue that the messages are apparently sent but does not get delivered. This is frustrating. There is not clear log that can be checked, and there is no clear sign that Signal servers has issues. This is regardless of using phone app or desktop app. The more I use #DeltaChat, the more I believe a centralized messaging is suboptimal. Signal have been quite unstable during the past few days for me regardless of the device, internet, and even city! #SignalApp
