I too am having problems with my Daedalus 0.11 wallet. Will not connect. Have tried all of the easy fixes to no avail. I plan to uninstall / delete Daedalus and reinstall. I see that the download page also has links for PGP signature and SHA256 Checksum. I am unfamiliar with these verification protocols. Should I follow instructions for both or just one? Do most people use these, or is simple download and install considered pretty safe? Thanks for you input.
To be clear, probably best to follow the instructions in the FAQ section that tells you not to uninstall but just delete the DB folder (sorry @Andy_Hendrikx!).
Thanks RobJF. I tried as you suggested to delte the DB folder, but the problem continues. Still not able to connect.
