We briefly distributed version 7.4.0 of SpiderOak One and Groups before determining that it could be unstable under poor network conditions. We have since returned to distributing version 7.3.0, and recommend that users on 7.4.0 downgrade. To do so, use your operating system's usual means to uninstall 7.4.0. Then download version 7.3.0 of One or Groups and install it. Your settings will be retained during this process.
We believe we have found the difficulty in 7.4.0 and are now testing 7.5.0 beta which we hope will combine 7.4.0's improvements with 7.3.0's stability. As we do not wish to repeat our mistake, we are testing it very carefully. For that reason it does not have a release date and will be released when fully tested.
