I have the Samsung Galaxy A50 and have been using the Message+app since getting this phone in February with no issues at all. Then last night after having used it several times throughout the day yesterday, it started saying message failed to every message I tried to send. I tried sending messages to different contacts and every message said message failed. I restarted my phone, rebooted the phone, uninstalled the app and then reinstalled it and still the same problem. Please help. I can text through the regular texting on the phone but it just isn't the same lol.
