Like @Darren_Murphy said, that all depends on each individual user’s device. Glide adapts to different regions to show numbers, dates, date pickers, and various other things appropriately for the user’s region.
My guess is that you have some users that have there device OS or Browser region set to US English for example instead of the correct region for their location, so everything is going to display in a way that’s normal for users in the USA.
Which country are your users located?
How do you normally view dates? (DD/MM/YYYY or MM/DD/YYYY)
Do you typically view times in 12 hour or 24 hour format?
Do you use , or . as a decimal indicator in numbers?
Do you use , or . as a thousands separator in numbers?
These are all things that Glide figures out based on the region that is set on a user’s device. In addition to that, Glide also automatically translates certain elements in the app, so everything displays in the correct language based on the user’s language settings. Under normal circumstances, it adapts to display everything correctly for each individual user based on their device settings.
