How to increase notifications text size of Oppo?

When we send a text message, we often notice the size of the text and whether it is big enough to read. But when we get a notification on our Oppo, it’s even more difficult to read.
The text size of the watch notification is very small and difficult to read for some people.
So how can we increase the text size of notifications on our watch?
Oppo firmware doesn't allow to change the text size of the notification text.
On Notify app we added the option to make both title and text all uppercase to make it more easier to read.

• The first step is to open the Notify app on your Android
• Open app notifications
• Go on the general settings (see Gear icon)
• Enable uppercase text option

Optionally, you may want to enable uppercase mode only for a specific app, to do so, enable uppercase option on the Display section of the single app
