Since last update everything - fonts and pictures - is too small to read (on my tablet).
Welcome and thanks for reporting. Could you share a screenshot? The last update (SeriesGuide 51) should not have changed anything regarding font sizes.
Everything looks as expected. What font in particular are you talking about?
Hm, the clock font top right is also larger. So I suggest looking at your device’s settings (likely under “Display”) if the font size was changed.
Update: I verified on my device that changing the font size still works. So this likely is an issue with your device (e.g. settings or issue, maybe check for software updates or reboot?).
