Shes entered into the Roehampton juniors in the first week of Wimbledon and Wimbledon juniors itself. Shes only 15, maybe shes focusing on doing well in the junior events where she might fancy her chances of a good run?
It was a big emotional rollercoaster playing in adult qualis with big wins and a lot of attention, playing in front of a relatively big crowd and then a pretty comprehensive lost in FQR. It's probably hard to get yourself back up to playing juniors.
This is all part of the learning curve though. A bit like Katie Boulter winning Nottingham last year and then going out of the next tournament in the first round. Part of the ability to be a top player is to be able to deal with that and smooth out the emotions so this is excellent experience.
