@Phil3 ,
You didnt specify which type of phone you started using now, but here the official info from the Litchi FAQ page of the User Guide.
10. I purchased the app on one device, can I install it on other devices?
You can install the app on as many devices as you want as long as they use the same platform and the same “main” account (Google, Apple or Amazon) that was used for the original purchase. If you wish to use Litchi on two or more platforms you will need to purchase it on each one.
If that doesnt answer your question, provide more info.
Thanks for the fast response
I now use a Huawei P40 Pro.
Since I still had Google services on my old mobile phone (Huawei P20 Pro) and bought it there in the Playstore, this will no longer work with my Huawei P40 Pro without Google services if I understand the answer correctly?
Both phones use Google Play to download apps, dont they?
It could be an issue of Login/password changes that you used on your old phone vs your new phone.
No, unfortunately the Huawei P40 Pro no longer supports Google services and therefore no Google Play. The Huawei P40 Pro uses the Huawei AppGallery to download the apps.
