I too get this issue BUT I don’t have to re-install the app, just clear the sync data by clicking the little red X beside the Tablo name on the “Connect to Tablo” screen.
Takes about a minute, connect to Tablo comes back up. Sometimes I have to re-scan to see the Tablo again (most of the time I do not).
Click connect under the new Tablo area.
Not sure if this is faster or slower than just deleting the app but it works for me. Still annoying, it does seem as it has been happening more often the last couple of months.
