Apps are closing when opened

Good morning. I have several apps that I use to listen to the radio. There are Dutch but also Belgian radio apps on my phone.
Since this morning all the Dutch apps are not working anymore. They close as soon as I open them ……
on the iPad I have no problems with them …. I deleted one app and reinstalled it but it still doesn’t work. Any idea what causing this?
Thank you!

Hi!

Which Fairphone do you use? On my Fairphone 5 there is sometimes a bug with the Bluetooth connection. There are some (audio) apps that behave similarly to your description sometimes. After I disable and reenable Bluetooth they work normally again.

Hi. The FP 4. This never happened before. The apps just don’t open at all

Hello again.
Problem solved. It is a bug in the radio app. They are working on it.
Bye! Thanks for your reaction!
