About 2 weeks ago, I installed Printoid Premium on my phone (the paid version). The only time I have been able to connect to the printer/Pi/ whatever it connects to, was during the initial installation. Since then, it just keeps telling me "Unable to Connect"...even at home, on my wifi. I know Octoprint is connected to the network (wireless) because I can pull it up on my laptop, but it's no go on my phone. I've tried several of the published "troubleshoot" ideas, but none have worked. Any ideas ???? FWIW..I have a Galaxy Note 8.
