I tested Shell Recharge and it installs ok for me from App Lounge, finds location accurately and gives an indication (poor topology) of fuel stations. Edit I first used A15 but I do not think it relevant; then install went fine from Aurora store on A13, in this case the app is not performing well, I think the app requires Account sign in, it was just slow to get location. Works satisfactory except again same poor topology in A13.
This sounds much more an app-lounge problem. Please follow that hashtag, there are many recent posts, even suggesting that spoofing the device might help. Also App Lounge cannot show or install many "common" apps (#8738) · Issues · e / Backlog · GitLab and App Lounge hangs on many "common" apps
Shell Recharge may be handicapped in use by MapsLibre. This was mentioned in the context of topology not nicely rendered in the case of another app Tractive Tractive App and Open Street Map - #5 by tcecyk
