I can't find any way to submit a ticket or issue complaint directly to twitter but twitter DMs is my main form of communication with a few family members around the world. After the latest update i am no longer getting notifications for DMs. And yes they are turned on in the settings. I cleared the cache. Uninstalled & reinstalled. Restarted my phone. All the normal troubleshooting. This NEEDS to be fixed. I'd give negative stars just for this if i could.
