From the Spike dev team: “IMPORTANT/URGENT ANNOUNCEMENT. ALL USERS PLEASE READ!!! Hello, Spikers. Please read this important/urgent announcement and act accordingly. This is an urgent matter and applies to EVERYONE. If you want to continue using Spike then please follow the guide listed in the announcement ASAP. Thanks!” https://spike-app.com/ignition-announcement/ Just in case you have’t seen it on Facebook, Apple are revoking the compatibility certificate which enables Spike to run on iPhones. The team have come up with the workaround linked above, but it needs to be done as a matter of urgency as it’ll stop working tomorrow, 6th April 2019. There’s detailed instructions, just follow the steps and you’ll be fine!
