A good place to check is if you look at one of the guides (Welcome Topic, The Big Photo Guide, The Big Testing Guide) and see if all the table/photos/lists etc all look good. So no giant photos, no tiny photos, the tables all fit on your screen (or are scrollable), etc. That sort of thing.
Not noticed any formatting fails on the forum. Only annoyance using the phone is the lack of product pictures on discontinued items on the main site… until you turn to landscape when they appear.
Very odd but not really a problem as long as people know to rotate their phone.
Just to clarify, I’m thinking of posted content rather than forum architecture. Some of the menus are squiffy, etc but they’ve already been raised with the glitch people.
Not noticed anything standout odd on my hauwei mate 20 pro. In fact it’s one of the better sites.
Only issue maybe is the reply box? Keyboard takes up 50% of the screen like normal, but the text box is only around 20% so around 7 lines of text. Great big logo and topic on the top of the page and a huge reply button below to post it.
Feel it could be formatted better so some of the topic was visible or more screen space for the reply box.
