Texts disappearing in Google Messages, users report
The tread was first posted back in 2019 but the latest comments are just a few days old. It seems that it’s a known issue still not fixed completely by Google. There was a similar bug in Pixel 3 devices in 2018 when SMS texts were mislabelled and disappeared in Google Messages, but the latest problem is not tied to a specific model or manufacturer. Users report vanishing messages on Motorola, Lenovo, Huawei, LG, and Pixel devices as well.
The usually suggested solutions like restarting the phone, clearing the cache or rolling back to a previous version of the app don’t seem to resolve the issue. Judging by the date of the original thread, it’s been a year without a fix. We’ve reached Google to get an official statement on the matter and will keep you updated.
